  • Initial Experience with a Cone-beam Breast Computed Tomography-guided
           Biopsy System

    • Authors: Posy J Seifert, Renee C Morgan, David L Conover, Andrea L Arieno

      Journal of Clinical Imaging Science 2017 7(1):1-1
      Objective: To evaluate our initial experience with a cone-beam breast computed tomography (BCT)-guided breast biopsy system for lesion retrieval in phantom studies for use with a cone-beam BCT imaging system. Materials and Methods: Under the Institutional Review Board approval, a phantom biopsy study was performed using a dedicated BCT-guided biopsy system. Fifteen biopsies were performed on each of the small, medium, and large anthropomorphic breast phantoms with both BCT and stereotactic guidance for comparison. Each set of the 45 phantoms contained masses and calcification clusters of varying sizes. Data included mass/calcium retrieval rate and dose and length of procedure time for phantom studies. Results: Phantom mass and calcium retrieval rate were 100% for BCT and stereotactic biopsy. BCT dose for small and medium breast phantoms was found to be equivalent to or less than the corresponding stereotactic approach. Stereotactic-guided biopsy dose was 34.2 and 62.5 mGy for small and medium breast phantoms, respectively. BCT-guided biopsy dose was 15.4 and 30.0 mGy for small and medium breast phantoms, respectively. Both computed tomography biopsy and stereotactic biopsy study time ranged from 10 to 20 min. Conclusion: Initial experience with a BCT-guided biopsy system has shown to be comparable to stereotactic biopsy in phantom studies with equivalent or decreased dose.

      Bronchial artery aneurysm (BAA) is a rare vascular phenomenon. This review highlights a case of a BAA that was complicated by the presence of a bronchial artery to pulmonary artery (BA-PA) fistula, consequently presenting a unique challenge to management. BAAs have a strongly reported risk of rupture resulting in life-threatening hemoptysis. Embolization has thus become routine for the management such severe cases. The management of incidentally found anomalies is less obvious, but prophylactic embolization is a generally accepted practice. In this report, we review some of the risks and benefits associated with BAA embolization with specific consideration of the challenges in cases of co-existing BA-PA fistula.

      Laparoscopic adjustable gastric banding (LAGB) is a bariatric procedure that is being performed with increasing frequency as an alternative management option for morbid obesity. Several common complications have been reported including gastric band slippage and associated pouch dilatation, intragastric erosion of the band, gastric wall perforation, and abscess formation. We present a case of gastropericardial fistula occurring nine years after an LAGB. There have been no previous documented cases of the complication after this procedure.

  • Elastography-targeted Thyroid Nodule Aspiration: A Novel Approach

    • Authors: Elliot Landau, Danielle Del Re, Bina Kviatkovsky, Aryeh Rothstein, Jonathan Scheiner, Cheryl Lin

      Abstract: Elliot Landau, Danielle Del Re, Bina Kviatkovsky, Aryeh Rothstein, Jonathan Scheiner, Cheryl Lin
      Journal of Clinical Imaging Science 2017 7(1):4-4
      Objectives: Since 2009, the rate of nondiagnostic (ND) thyroid nodule fine-needle aspiration (FNA) has ranged from 2% to 20%. A ND result can cause further patient morbidity secondary to repeated procedures and delay in diagnosis. The use of real-time strain elastography (RTE) in determining nodule malignant risk has gained considerable focus recently. A less studied area where RTE may prove beneficial is its role in targeting areas for FNA. Our hypothesis is that FNA performed in concurrence with RTE will show a decreased rate of ND results leading to fewer repeated FNA. Materials and Methods: The Institutional Review Board approval was obtained. A retrospective review of all thyroid nodule FNA from January 1, 2011, to January 1, 2014, was performed with review of nodule size, presence of microcalcifications, vascularity, solid components, patient age, and gender. Cases were separated based if RTE was done before FNA or not. Pathology reports were reviewed to assess for specimen adequacy. Statistical comparison was performed using SAS analysis software. Results: A total of 221 specimens were reviewed, with RTE performed on 140 cases (63.4%). Both groups were similar in demographics and previously described nodule characteristics. The ND rate when RTE was not performed was 16% (13/68) compared to 10% when RTE was performed (14/126). The difference was not found to be statistically significant, P = 0.205. Conclusions: The presence of an elastogram failed to demonstrate a significant decrease in ND FNA rates although these results may be secondary to study design. Further evaluation with prospective trials using larger sample size may ultimately detect increased accuracy of RTE-targeted FNA.

      Journal of Clinical Imaging Science 2017 7(1):5-5
      A 4-month-old infant presented with a painless swelling overlying the left angle of mandible. Ultrasound and magnetic resonance imaging (MRI) revealed a large lesion replacing the entire left parotid gland, with multiple enlarged vessels. Homogeneous enhancement of the lesion was seen on the postcontrast MRI scans. Based on the imaging features, a diagnosis of infantile hemangioendothelioma of the parotid gland was offered. This helped in avoiding any further invasive testing.

      Vaginal bleeding in the first trimester has wide differential diagnoses, the most common being a normal early intrauterine pregnancy, with other potential causes including spontaneous abortion and ectopic pregnancy. The incidence of ectopic pregnancy is approximately 2% of all reported pregnancies and is one of the leading causes of maternal mortality worldwide. Clinical signs and symptoms of ectopic pregnancy are often nonspecific. History of pelvic pain with bleeding and positive β-human chorionic gonadotropin should raise the possibility of ectopic pregnancy. Knowledge of the different locations of ectopic pregnancy is of utmost importance, in which ultrasound imaging plays a crucial role. This pictorial essay depicts sonographic findings and essential pitfalls in diagnosing ectopic pregnancy.

  • Gastropleural Fistula with Aortic Intramural Involvement

      Journal of Clinical Imaging Science 2017 7(1):7-7
      Gastropleural fistula is a relatively rare complication that can be seen as a result of traumatic, nontraumatic, benign, and neoplastic etiologies. Most commonly, these are found in patients with diaphragmatic herniation or prior thoracic surgery. Aortoenteric fistulas are rare communications typically between the abdominal aorta and bowel. We present a rare case of an 88-year-old male who developed a gastropleural fistula with erosions into the wall of the descending thoracic aorta. Computed tomography (CT) is a leading modality in evaluation of suspected gastropleural or aortoenteric fistulas given the quick scan time and widespread availability. Prompt diagnosis is essential and requires an understanding of appropriate CT protocols and CT imaging appearance.

  • Computer-aided Detection Fidelity of Pulmonary Nodules in Chest Radiograph

    • Authors: Nikolaos Dellios, Ulf Teichgraeber, Robert Chelaru, Ansgar Malich, Ismini E Papageorgiou

      Aim: The most ubiquitous chest diagnostic method is the chest radiograph. A common radiographic finding, quite often incidental, is the nodular pulmonary lesion. The detection of small lesions out of complex parenchymal structure is a daily clinical challenge. In this study, we investigate the efficacy of the computer-aided detection (CAD) software package SoftView™ 2.4A for bone suppression and OnGuard™ 5.2 (Riverain Technologies, Miamisburg, OH, USA) for automated detection of pulmonary nodules in chest radiographs. Subjects and Methods: We retrospectively evaluated a dataset of 100 posteroanterior chest radiographs with pulmonary nodular lesions ranging from 5 to 85 mm. All nodules were confirmed with a consecutive computed tomography scan and histologically classified as 75% malignant. The number of detected lesions by observation in unprocessed images was compared to the number and dignity of CAD-detected lesions in bone-suppressed images (BSIs). Results: SoftView™ BSI does not affect the objective lesion-to-background contrast. OnGuard™ has a stand-alone sensitivity of 62% and specificity of 58% for nodular lesion detection in chest radiographs. The false positive rate is 0.88/image and the false negative (FN) rate is 0.35/image. From the true positive lesions, 20% were proven benign and 80% were malignant. FN lesions were 47% benign and 53% malignant. Conclusion: We conclude that CAD does not qualify for a stand-alone standard of diagnosis. The use of CAD accompanied with a critical radiological assessment of the software suggested pattern appears more realistic. Accordingly, it is essential to focus on studies assessing the quality-time-cost profile of real-time (as opposed to retrospective) CAD implementation in clinical diagnostics.

  • Asymptomatic Urolithiasis Complicated by Nephrocutaneous Fistula

      Asymptomatic spontaneous nephrocutaneous fistula is a rare and severe complication of chronic urolithiasis. We report a case of 56-year-old woman with a nephrocutaneous fistula (NFC) which developed from a superinfected urinoma following calyceal rupture due to an obstructing calculus in the left ureter. The patient was clinically asymptomatic and came to the emergency department for a painless left flank fluctuating mass. This urinoma was superinfected, with a delayed development of renal abscesses and perirenal phlegmon found on contrast-enhanced uro-computed tomography (CT), responsible for left renal vein thrombophlebitis and left psoas abscess.. Thereafter, a 99 mTc dimercaptosuccinic acid (DMSA) scintigraphy revealed a nonfunctional left kidney, leading to the decision of left nephrectomy. Chronic urolithiasis complications are rare and only few cases are reported in medical literature. A systematic medical approach helped selecting the best imaging modality to help diagnosis and treatment. Indeed, uro-CT scan and renal scintigraphy with 99 mTc-DMSA are the most sensitive imaging modalities to investigate morphological and functional urinary tract consequences of NFC, secondary to chronic urolithiasis.

      Congenital uterine arteriovenous malformation (AVM) is an extremely rare condition with <100 cases documented in literature. We report multiparous women presenting to us with a history of postcoital bleed. Initial Doppler ultrasonography was consistent with features suggestive of AVM. Subsequently, computed tomography (CT) angiography confirmed the diagnosis. Embolization was chosen as the treatment because of the large extension of AVM and the risk of hemorrhage during hysterectomy. The patient was discharged in a stable condition with a plan of repeat embolization in the next setting. At 6 and 12 weeks of follow-up, she did not experience any further episodes of bleed. The purpose of this case report is to highlight the salient clinical features, diagnosis, and the management options available for this rare clinical condition.

      Objectives: We aimed to prospectively assess the diagnostic value of apparent diffusion coefficient (ADC) measurement in the differentiation of benign and malignant mediastinal lymphadenopathies. Materials and Methods: The study included 63 consecutive patients (28 women, 35 men; mean age 59.3 years) with 125 mediastinal lymphadenopathies. Echoplanar diffusion-weighted magnetic resonance imaging of the mediastinum was performed with b-factors of 0 and 600 mm2/s before mediastinoscopy and mediastinotomy, and ADC values were measured. The ADC values were compared with the histological results, and statistical analysis was done. P < 0.05 was considered statistically significant. Results: The mean ADC value of malignant mediastinal lymphadenopathy (1.030 ± 0.245 × 10−3 mm2/s) was significantly lower (P < 0.05) when compared to benign lymphadenopathies (1.571 ± 0.559 × 10−3 mm2/s). For differentiating malignant from benign mediastinal lymphadenopathy, the best result was obtained when an ADC value of 1.334 × 10−3 mm2/s was used as a threshold value; area under the curve 0.848, accuracy 78.4%, sensitivity 66%, specificity of 86%, positive predictive value 76.7%, and negative predictive value of 79.2%. Interobserver agreement was excellent for ADC measurements. Conclusions: ADC measurements could be considered an important supportive method in differentiating benign from malignant mediastinal lymphadenopathies.

  • Radiologic-Pathologic Correlation: Acellular Dermal Matrix
           (Alloderm®) Used in Breast Reconstructive Surgery

      Journal of Clinical Imaging Science 2017 7(1):13-13
      Acellular dermal matrix (ADM) such as Alloderm® is sometimes used in tissue reconstruction in primary and reconstructive breast surgeries. As ADM is incorporated into the native tissues, the evolving imaging findings that would correlate with varying degrees of host migration and neoangiogenesis into the matrix can be challenging to recognize. In the setting of a palpable or clinical area of concern after breast reconstructive surgery following breast cancer, confident diagnosis of a mass representing ADM rather than recurring or developing disease can be challenging. Such diagnostic imaging uncertainties generally result in short-term imaging and clinical follow-up, but occasionally, biopsy is performed for histopathological confirmation of benignity. A case of biopsy-proven Alloderm® is described. To the best of our knowledge, this is the first radiologic-pathologic correlation of ADM in the literature.

      Given the widespread use of transjugular intrahepatic portosystemic shunt (TIPS) creation for the treatment of portal hypertensive complications, a working knowledge of portal venous anatomy is critical for interventional radiologists. The right portal vein – which is most commonly accessed during TIPS – is subject to various anatomic variants that may potentially impact procedure success. This pictorial essay characterizes the anatomic patterns of the right portal vein branching in terms of type and frequency based on case series review. The work also explains the potential procedural implications of the right portal vein anatomic variations as they pertain to TIPS technical success.

      Although large bowel obstruction (LBO) is less common than small bowel obstruction, it is associated with high morbidity and mortality due to delayed diagnosis and/or treatment. Plain radiographs are sufficient to diagnose LBO in a majority of patients. However, further evaluation with multidetector computed tomography (MDCT) has become the standard of care to identify the site, severity, and etiology of obstruction. In this comprehensive review, we illustrate the various causes of LBO emphasizing the role of MDCT in the initial diagnosis and detection of complications along with the tips to differentiate from disease which can mimic LBO.

      Objective: The aim of this study was to evaluate the mandibular lingual foramina (LF) and canals and their anatomic variations using cone-beam computed tomography (CBCT) technology in a Lebanese population. Materials and Methods: In this study, we analyzed CBCT images of 90 adult Lebanese patients (41 males and 49 females). We assessed the number and location of the LF. In additional, we measured: (a) The distance from both the alveolar crest and the inferior border of the mandible to the LF and (b) the length of the lingual canals (LCs). The data obtained was analyzed statistically using Shapiro–Wilk normality test, t-test, Chi-square, and Fisher's exact tests. Statistical significance was set at 0.05. Results: In our sample, the LF and canals were present in 93.33% of the CBCT analyzed, and the majority (76.64%) was located above the genial tubercles. The distance from the foramen of the superior and the inferior LCs to the alveolar crest was 16.24 ± 2.82 mm and 25.49 ± 2.43 mm, respectively. The distance from the foramen of the superior canal to the inferior border of the mandible was 14 ± 2.32 mm. The mean length of the superior canal was 5.81 ± 1.6 mm and 4.25 ± 1.2 mm for the inferior one. There were no gender-related differences in the anatomic characteristics of the LF and canals except for the distance measured from the superior canal foramina to the alveolar crest where the measurement was significantly greater in males compared to females. Neither the number of canals nor the positions of the foramina were different between males and females. Conclusion: Within the limits of this study, we concluded that in our sample of Lebanese adults, there was substantial variability in the LF and canals anatomy and location.

      Ewing sarcoma, including classical Ewing sarcoma of the bone and primitive neuroectodermal tumors arising in bone or extraosseous primary sites, is a highly aggressive childhood neoplasm. We present two cases of Ewing sarcoma arising from the vagina in young girls. Previously reported cases in literature focused on their pathologic rather than radiographic features. We describe the spectrum of multimodality imaging appearances of Ewing sarcoma at this unusual primary site. Awareness of vaginal Ewing tumors may facilitate prompt diagnosis and lead to a different surgical approach than the more commonly encountered vaginal rhabdomyosarcoma.

      Renal angiomyolipomas (AMLs) and pulmonary lymphangioleiomyomatosis (LAM) are the most common tumors of the perivascular epithelioid cell (PEComa) family. Both may be associated with tuberous sclerosis (TS) complex. Epithelioid AML (EAML) is a rare variety of AMLs, with a potential aggressive behavior. There are few reports in the English literature addressing on the imaging findings of renal EAMLs, which are considered nonspecific. We present the sonographic, computed tomographic, and magnetic resonance imaging findings of a renal EAML in a pregnant woman with concomitant pulmonary lesions indicative of LAM, without stigmata of TS. We conclude the importance of considering EAML as a possible diagnosis in the presence of a large renal mass with high cellular content and small amounts of fat in the coexistence of pulmonary LAM.

      Context: Ectopic neurohypophysis (EN) refers to an interrupted, nonvisualized, and thinned out pituitary stalk with ectopic location of the posterior pituitary gland. Concurrent extra-pituitary cerebral and extra-cranial anomalies have been rarely reported in patients of EN. Aim: The aim of this study was to evaluate the magnetic resonance imaging (MRI) findings of extra-pituitary cerebral anomalies in pediatric patients of EN. Settings and Design: A hospital-based cross-sectional study was conducted in a tertiary care center. Subjects and Methods: The study group comprised eight pediatric patients of EN associated with extra-pituitary cerebral or vascular anomalies. Clinical and biochemical assessment was done in all patients. Results: Out of the total eight patients with EN, MRI showed interrupted pituitary stalk in five patients (62.5%) and nonvisible pituitary stalk in three patients (37.5%). Ectopic posterior pituitary bright spot was demonstrated in median eminence in six patients (75%), faintly visualized in one patient (12.5%) and nonvisualized in another one patient. Statistical significant association was noted between pituitary gland height and patient's body height with the pituitary gland volume (P < 0.001). Varied extra-pituitary cerebral anomalies encountered in our patients ranged from isolated anomalies such as optic nerve hypoplasia in three patients (37.5%), corpus callosum dysplasia in four patients (50%), agyria-pachygyria complex in two patients (25%), and intracranial vascular anomalies in two patients to syndromic association of tuberous sclerosis in one patient. Conclusion: Identifying and reporting of associated extra-pituitary cerebral anomalies in patients with EN are crucial in assessing the overall neurological outcome of such patients.

      Objectives: Conventional methods of imaging neuroendocrine tumors with computed tomography, magnetic resonance imaging, indium-111-octreotide, or radiolabeled metaiodobenzilguanidine scintigraphy have limitations. This pilot study tried to improve the localization of these tumors with fluorine-18-fluorodihydroxyphenylalanine (F-DOPA) positron-emission tomography (PET) scanning. Materials and Methods: We studied 22 patients, the majority of whom were referred with clinical diagnosis or suspicion of carcinoid (n = 11), neuroendocrine tumors (n = 7) or pheochromocytoma/paraganglioma (PGL) (n = 4). The comparison was made with the prior conventional imaging. Results: The F-DOPA findings were compared with the results of subsequent surgery (2), endoscopy (1), or a long-term follow-up (mean duration, 49 months) for 17 patients. Two patients were lost to follow-up. Foci of F-DOPA deposition were detected in eight patients (final diagnosis of carcinoid in six, of neuroendocrine tumors in one, and of PGL in another). Comparison with the final diagnoses revealed concordance in 16 of the 22 patients. F-DOPA results appeared superior to those obtained with conventional imaging. Despite the small number and diagnostic heterogeneity, in a substantial fraction of patients F-DOPA PET added information relevant to clinical management. Conclusion: F-DOPA scanning added prognostic value, particularly when multiple abnormal foci versus a negative examination were considered.

      Objectives: We aimed to test the predictive value of antenatal umbilical coiling index (aUCI) among a prospectively recruited cohort of antenatal women. Methods: Women with singleton pregnancies were recruited at their second-trimester scan. Images of the umbilical cord were used to calculate the aUCI. Pregnancy and birth outcomes were recorded and statistical associations between aUCI and small for gestational age (SGA) using international standard birth weight centiles and preterm birth were investigated (n = 430). Results: aUCI results were consistent with the literature and showed good reproducibility between observers. Abnormal aUCI was not associated with SGA, but there was a statistical association with preterm birth (odds ratio 3.3 (95% confidence interval 1.4–7.7,P = 0.003). The sensitivity, specificity, and positive and negative predictive values for preterm birth were 47.6%, 76.9%, 9.6%, and 96.6%, respectively. Conclusions: The coiling index is unlikely to be useful in clinical practice as a screening tool for preterm birth owing to limited predictive value. We exclude a statistically or clinically significant association between abnormal coiling and SGA.

      Introduction: The objective of this study is to determine whether a radiology module, together with online spaced education, helps students of an integrated problem-based learning (PBL) curriculum increase their radiology knowledge and long-term retention. Materials and Methods: Second-year students at the American University of Antigua College of Medicine participated in small groups of ten students each into two 2 h of radiology laboratories. The study comprised two cohorts: winter and fall 2013 students (control group) and 2014 students (experimental group). Both groups used face-to-face PBL. The students of the experimental group received additional online-spaced education. The skills were assessed for both groups before the beginning of laboratories and 4 weeks and 7 months after laboratories. Results: There was no significant difference on pretest between the control and experimental groups. On completion of the radiology laboratories, comparison of test results before and after training showed net improvement for both groups. The corresponding difference for the experimental group was higher compared to the one for the control group (7.83 vs. 6.21, P < 0.001). The difference between the scores on delayed test and pretest showed that the students of both groups demonstrated average knowledge improvement even though their level of performance was slightly below the posttest. The corresponding difference for the experimental group did not differ much from the posttest (P > 0.05), and no significant difference of scores was observed 7 months later for either group. Further, a higher percentage of the students in the experimental group strongly agreed that their learning objectives were met (92% vs. 71%, P > 0.001), and this trend persisted throughout the study. Conclusion:Online spaced education combined to a face-to-face PBL enhances not only the student's knowledge of basic radiology along with his/her self-assessment skills but also the long-term retention of radiology material and satisfaction with the integrated interactive system-based module. Future research is needed to see if medical students in need of additional education support may benefit from spaced education in the field of remediation.

      Urinary bladder carcinoma (UBC) is the ninth most common malignancy and the second most common urological malignancy after prostate cancer in men. Thoracic metastases occur in more than half of those with muscle-invasive disease, and these generally assume the form of multiple solid parenchymal lesions characteristic of hematogenous seeding of the lung. Unusual patterns of thoracic spread of UBC have also been described albeit sporadically in the form of case reports and series. The aim of our case series is to provide illustrations of several atypical patterns of thoracic involvement by UBC such as isolated mediastinal lymphadenopathy, cavitary lung metastases, malignant pleural effusion, endobronchial disease, and pulmonary tumor embolism. This review is meant to highlight the intersection of the fields of urological oncology and thoracic radiology in the care of patients with UBC.

      Objectives: To assess the utility of dynamic imaging namely, wash-in and wash-out characteristics through multidetector contrast-enhanced computed tomography in differentiating benign and malignant pulmonary masses. Materials and Methods: Seventy-three patients who were suspected to have malignant pulmonary mass on the basis of clinical symptoms and chest radiograph were included in the study. All the patients underwent multidetector computed tomography scanning, and three series of images were obtained for each patient-noncontrast, early enhanced, and 15 min delayed enhanced scans. Computed tomography (CT) findings were assessed in terms of washin, absolute, and relative percentage washout of contrast. Biopsy of the mass was done and sent for histopathological evaluation. Sensitivity, specificity, and area under curve for diagnosing malignancy in the lung masses were calculated by considering both the wash-in and wash-out characteristics at dynamic CT and plotting the receiver operating curve after the final diagnosis which was obtained by histopathological evaluation. Results: Threshold net enhancement (washin) value of >22.5 HU had sensitivity, specificity, and diagnostic accuracy of 88.5%, 57.1%, and 82%, respectively, in predicting malignancy. Threshold relative percentage washout of <16.235% had 98.1%, 85.7%, and 94% sensitivity, specificity, and diagnostic accuracy, respectively, and threshold absolute percentage washout of <42.72% had 98.1%, 95.2%, and 95% sensitivity, specificity, and diagnostic accuracy, respectively, in predicting malignancy. Conclusion: Threshold net enhancement (washin), absolute and relative washout percentages can be used to predict malignancy with very high diagnostic yield, and possibly obviate the need of invasive procedures for diagnosis of bronchogenic carcinoma.

      Objective: Diabetes mellitus, smoking, dyslipidemia, and obesity play an important role in the etiology of erectile dysfunction, particularly in cases with vascular insufficiency. These risk factors also target the lungs due to their systemic effects. Materials and Methods: Patients with penile vascular insufficiency determined at Doppler ultrasonography and undergoing thoracic computerized tomography for various reasons were included in this study. A history of acute thoracic trauma, pneumonic consolidation, or pelvic surgery and trauma were regarded as exclusion criteria. Results: Thirty-seven male patients with identified vascular insufficiency (age 54.48 ± 13.62 years) were enrolled. Mass lesions with a malignant morphology were present in two patients. The most common mediastinal/vascular pathology was atherosclerosis, while the most common parenchymal lesion was emphysematous aeration. Other findings included parenchymal fibrotic bands, atelectasis, interstitial thickening, bronchiectasis, air trapping, aortic aneurysm, a dilated pulmonary artery, hiatal hernia, and pericardial effusion. Conclusion: Erectile dysfunction may be an early sign of cardiovascular diseases. Care must be taken in terms of existing or potential pulmonary pathologies in these patients due to their sharing common risk factors with systemic effects.

      We report two cases of uterine lipoleiomyoma in postmenopausal women of ages 52 and 55 years, who presented with complaints of leukorrhea and lower abdominal pain, respectively. Lipoleiomyoma is a rare benign variant of leiomyoma, having an incidence of 0.03%–0.2%. These are benign pelvic tumors which are usually asymptomatic and commonly occur in obese postmenopausal women. However, they can occasionally present with typical leiomyoma symptoms. Imaging plays a crucial role in the diagnosis of benign pelvic tumors. Ultrasonography is the first imaging modality for diagnosis of pelvic tumors in females. Computed tomography and magnetic resonance imaging are specific in demonstrating the uterine origin and fat component.

      Objectives: This study was undertaken to estimate the incidence and burden of cerebral microhemorrhage (CM) in patients with heart disease who underwent cardiopulmonary bypass (CPB), as detected on susceptibility-weighted imaging (SWI), a magnetic resonance (MR) sequence that is highly sensitive to hemorrhagic products. Materials and Methods: With Institutional Review Board waiver of consent, MR imaging (MRI) of a cohort of 86 consecutive pediatric patients with heart failure who underwent heart transplantation evaluation were retrospectively reviewed for CM. A nested case–control study was performed. The CPB group consisted of 23 pediatric patients with heart failure from various cardiac conditions who underwent CPB. The control group was comprised of 13 pediatric patients with similar cardiac conditions, but without CPB history. Ten patients in the CPB group were female (age: 5 days to 16 years at the time of the CPB and 6 days to 17 years at the time of the MRI). The time interval between the CPB and MRI ranged from 11 days to 4 years and 5 months. Six patients in the control group were female, age range of 2 days to 6 years old. The number of CM on SWI was counted by three radiologists (PK, EK and DK). The differences in number of CM between groups were tested for significance using Mann–Whitney U-test, α = 0.05. Using the univariate analysis of variance model, the differences in number of CM between groups were also tested with adjustment for age at MRI. Results: There are statistically significant differences in CM on SWI between the CPB group and control group with more CM were observed in the CPB group without and with adjustment for age at MRI (P < 0.001). Conclusions: Exposure of CPB is associated with increased prevalence and burden of CM among pediatric patients with heart failure.

      Enlargement of the mandibular canal is a rare radiological finding. Clinically, it may or may not be associated with sensory deficits. We report four cases of widening of the mandibular canal observed with various methods of imaging with different clinical characteristics. We describe this unique radiological finding and elaborate the importance of quality assessment of the imaging that is vital for accurate diagnosis and treatment planning. Clinicians should be mindful when assessing the imaging whenever the size of the mandibular canal is implicated. The case ranged from a benign tumor to malignancy, radiological errors, and artifacts. A more superior imaging or treatment modality was necessary to ascertain the diagnosis.

      pCONus is a stent-like endovascular device which aids in retention of coils within wide-necked bifurcation aneurysms. It is retrievable even after complete deployment and is detached electrolytically. The pCONus aided coiling of wide-necked bifurcation aneurysms has a high technical success rate and a good safety profile. Different complications have been described in literature with the usage of pCONus. This case report describes a unreported complication of inappropriately deployed pCONus device.

      The presence of simultaneous two ectopic foci of thyroid tissue (dual ectopic thyroid) is rare, and few cases have been reported in the literature. The ectopic thyroid tissue is an extremely uncommon embryological aberration due to the alterations occurring during the embryological development with incomplete migration of thyroid precursors. Commonly ectopic thyroid tissue is a midline structures, but the lateral location is possible but very rare. Ectopic thyroid is common in women and can vary in size from a microscopic focus to a few centimeters. The normal process of migration of the thyroid can be interrupted at various levels determining a lingual ectopy, a sublingual ectopic, prelaryngeal ectopy, or mediastinic ectopy. Intrathoracic and subdiaphragmatic organs are other sites where the ectopic thyroid tissue may be present. In most of the cases, ectopic tissue is a lingual thyroid and this condition can be totally asymptomatic, discovered incidentally, or occurs with symptoms such as dysphonia, dysphagia, dyspnea, and hemoptysis. Sublingual or suprahyoid ectopia is rare and even rarer are the cases of two foci of ectopic thyroid tissue simultaneously present. On imaging, the ectopic tissue shows the same characteristics of orthotopic thyroid tissue and similarly can undergo goiterous and cancerous transformation. We report a case of incidental dual ectopic thyroid in lingual and suprahyoid level in a 72 year old female patient, asymptomatic and with normal thyroid function, who underwent computed tomography (CT) angiography before vascular surgery for the treatment of carotid stenosis. The presence of a lingual thyroid can lead to a difficult and dangerous intubation, with possible fatal consequences. For this reason, the discovery of these abnormalities has totally changed the patient management who has been subjected to endovascular treatment, instead to the classical surgery.

      Objective: Conventional percutaneous transluminal angioplasty (PTA) for long lesions in the below the knee (BTK) arteries in patients presenting with critical limb ischemia (CLI) has high restenosis rates at 1 year. Our goal is to evaluate whether paclitaxel drug eluting balloons (DEB) have higher 1 year primary patency rates compared to conventional PTA. Methods: This is a single center, prospective, randomized trial that was conducted from June 2013 to December 2015. The aim of the study was to compare 1 year primary patency rates of DEB and PTA in BTK arteries in CLI patients. Inclusion criteria were patients presenting with CLI (Rutherford class 4 or greater), stenosis or occlusion ≥30 mm of at least one tibial artery, and agreement to 12 month evaluation. Exclusion criteria were life expectancy <1 year, allergy to paclitaxel, and contraindication to combined antiplatelet treatment. Follow up was performed by clinical assessment, ankle brachial pressure index, Doppler ultrasound imaging, and conventional angiogram if indicated. Primary end point was 1 year primary patency, and secondary end points were target lesion revascularization (TLR) and major amputation. Statistical analysis was performed using Fischer's exact test. Results: Ninety three patients with 106 lesions in the BTK arteries were enrolled in this study. One year primary patency was achieved in 26 (65%) and seven (17%) in the DEB and PTA groups (P = 0.006), respectively. TLR was performed in nine lesions (23%) and 29 lesions (71%) in DEB and PTA groups (P = 0.009), respectively. Major amputations occurred in one limb (2%) and two limbs (4%) in DEB and PTA groups (P = 0.6), respectively. Conclusion: Paclitaxel DEB has significantly higher 1 year primary patency rate associated with significantly less TLR than conventional PTA, following endovascular recanalization of BTK arteries in patients presenting with CLI.

      Background: The treatment of symptomatic partial rotator cuff tear has presented substantial challenge to orthopaedic surgeons as it can vary from conservative to surgical repair. Researches have established the influence of platelet rich plasma in healing damaged tissue. Currently very few data are available regarding the evidence of clinical and radiological outcome of partial rotator cuff tear treated with ultrasound guided platelet rich plasma injection in English literature. Materials and Methods: 20 patients with symptomatic partial rotator cuff tears were treated with ultrasound guided platelet rich plasma injection. Before and after the injection of platelet rich plasma scoring was done with visual analogue score, Constant shoulder score, and UCLA shoulder score at 8 weeks and third month. A review ultrasound was performed 8 weeks after platelet rich plasma injection to assess the rotator cuff status. Results: Our study showed statistically significant improvements in 17 patients in VAS pain score, constant shoulder score and UCLA shoulder score. No significant changes in ROM were noted when matched to the contra-lateral side (P < 0.001) at the 3 month follow-up. The study also showed good healing on radiological evaluation with ultrasonogram 8 weeks after platelet rich plasma injection. Conclusion: Ultrasound guided platelet rich plasma injection for partial rotator cuff tears is an effective procedure that leads to significant decrease in pain, improvement in shoulder functions, much cost-effective and less problematic compared to a surgical treatment.

      Primary pulmonary angiosarcoma is extremely rare. It is often characterized by a clinically indolent course and delayed diagnosis. To date, there have been <20 cases reported. By far, little article correlates the clinical presentation, the imaging findings with the pathology. The authors present a case of middle-aged gentleman with primary pulmonary epithelioid angiosacroma which we initially thought as tuberculosis (TB) infection. A 60-year-old gentleman, with a history of 6 months on and off blood stained sputum, was admitted for an episode of massive hemoptysis. Urgent computed tomography (CT) bronchial arteriogram excluded any dilated bronchial artery. Patchy consolidation with multiple small centrilobular ground-glass nodules was noted at left upper lobe. The bronchoscopy was negative for malignancy and infection. Autoimmune workup was negative. Despite negative bronchoscopy, fungal, acid-fast bacilli culture and cytology, and anti-TB treatment were empirically given. However, his hemoptysis was unresolved. He was followed up with high-resolution CT after a month showed an enlarging left upper lobe mass surrounding by a ground glass halo. Left thoracotomy and left upper lobe lobectomy were performed. Epithelioid angiosacroma was found in histology. Radiologic and clinical-pathological findings were correlated in this paper.

      Objectives: The objective of this study was to determine, using magnetic resonance imaging (MRI) of the lumbosacral spine from L1 to S1, the values of the normal sagittal diameter of the spinal canal (SCD), sagittal diameter of the dural sac (DSD), and the normal values of dural sac ratio (DSR) in a large nonsymptomatic adult population and to discriminate whether a vertebral canal is pathological or nonpathological for dural ectasia and/or stenosis. Materials and Methods: Six hundred and four patients were prospectively enrolled. All measurements were performed on MRI sagittal T1- and T2-weighted images. The 95% confidence interval (95% CI), defined as mean ± 1.96 standard deviation, was determined for each metric. The upper limit of 95% CI was considered the cutoff value for the normal DSR; the lower limit of 95% CI was considered the cutoff value for the normal SCD. Results: SCD cutoff values from L1 to S1 ranged from 14.5–10.1 mm (males) to 15.0–9.9 mm (females). DSD ratios at S1 and L4 level show a significant difference in male and female groups: 11% of S1/L4 values exceeded 1 in male group while only 4% of S1/L4 values exceeded 1 in female group. Mean DSR at each level was significantly higher in female patients than in male patients (P < 0.001), ranging from 0.70 to 0.56 (male) and from 0.82 to 0.63 (female). Conclusions: We determined the cutoff values for the normal DSR and for the normal SCD. Our findings show the relevant discrepancies with respect to literature data for diagnosis of lumbar stenosis and/or dural ectasia.

      Primary perivascular epithelioid cell tumor (PEComa) of the liver is a very rare tumor that originates from mesenchyma. Gastrointestinal tract with perivascular distribution is the most common anatomic sites of these tumors. Only few cases of hepatic PEComa have been described so far. Malignant PEComas exhibit aggressive behavior with poor prognosis, making early diagnosis crucial. Hereby, we report a 79-year-old female with unusually located mass in the liver. A partial curative hepatectomy has been done, and PEComa was diagnosed histopathologically. No evidence of recurrence was observed during the 6-month follow-up.

      Many children frequently fail extubation or require a prolonged period of positive pressure ventilation support after cardiac surgery. Pediatric cardiac Intensive Care Unit (PCICU) ultrasound (US) stands as a simple, basic bedside tool that can be performed by trained intensivists for the diagnosis with immediate implication on therapeutic decisions in multiple scenarios that physicians may face in PCICU. Bedside US is widely available, convenient, and inexpensive. This educational article based mainly on our own experience is highlighting the role of US in detecting the most common causes of respiratory weaning difficulties and extubation failure in postoperative cardiac children through proposed illustration and algorithm.

      Schwannomas are benign soft-tissue tumors that arise from peripheral nerve sheaths throughout the body and are commonly encountered in patients with neurofibromatosis Type 2. The vast majority of schwannomas are benign, with rare cases of malignant transformation reported. In this pictorial review, we discuss the magnetic resonance imaging (MRI) appearance of schwannomas by demonstrating a collection of tumors from different parts of the body that exhibit similar MRI characteristics. We review strategies to distinguish schwannomas from malignant soft-tissue tumors while exploring the anatomic and histologic origins of these tumors to discuss how this correlates with their imaging findings. Familiarity with the MRI appearance of schwannomas can help aid in the differential diagnosis of soft-tissue masses, especially in unexpected locations.

      Snapping pes anserinus syndrome is an often encountered cause of medial knee snapping. It results from impingement and translation of the gracilis tendon or semitendinosus tendon over the osseous structures of the knee during active flexion and extension. Ultrasonography is often the diagnostic imaging test of choice in cases of mechanical snapping. We report 2 cases of painful snapping pes anserinus and highlight the value of dynamic ultrasound in making an accurate diagnosis so as to direct care.

      Arteriovenous malformations (AVM) of the inferior mesenteric artery are rare. They may be primary (congenital or idiopathic) or secondary (acquired) after trauma or of iatrogenic origin. Of the abdominal AVM, the inferior mesenteric trunk is the least commonly involved. Most reported cases are of iatrogenic origin, resulting from colon surgery. Only 17 cases have been described and published in the literature. The objective of this work is to make known a case treated in our center. We present a case of 73-year old male, who came to the emergency service with symptoms of abdominal distension, pain lasting 48 hours along with months of diarrhoea. CT scan and an abdominal CT angiography showed a massive left-sided congestive colitis due to idiopathic inferior mesenteric arteriovenous malformation. In our case, the decision was to carry out the treatment in two stages. Embolisation was performed in the first stage in order to decrease the blood flow and the risk of intraoperative bleeding, followed by resective surgery of the affected colon.

      Objective: Hematological malignancies very rarely involve the breast. The aim of this study is to retrospectively evaluate B-mode ultrasound (US) and elastography (ES) findings of breast involvement by hematologic malignancies with clinical outcomes. Materials and Methods: All core-needle biopsy results that were performed at our tertiary breast center from January 2013 to September 2016 were searched. Our search revealed 9 patients with breast involvement either by leukemia or lymphoma. All patients were examined using B-mode US and ES. US and ES findings were analyzed with the consensus of two radiologists, and clinical outcomes were noted. Results: The mean age of the study population was 41.6 years (range, 20–83 years). Two patients showed diffuse hypoechoic parenchymal infiltration. The elasticity assessments of these lesions were soft and intermediate. The remaining 7 patients had mass lesions. The elasticity assessment of these masses according to Breast Imaging Reporting and Data System US was as follows: Soft (n = 1), intermediate (n = 4), high (n = 2). Conclusions: It is important to consider that hematologic malignancies may appear as soft or intermediate lesions on ES. Patients' history and clinical background should help us to consider breast involvement. In addition, the clinical outcomes may not be related with elasticity assessments.
