  • Coexistent Non–Small Cell Carcinoma and Small Cell Carcinoma in a
           Patient Presenting with Hyponatremia

    • Abstract: Despite recent advances in screening methods, lung cancer remains the leading cause of cancer-related deaths worldwide. By the time lung cancer becomes symptomatic and patients seek treatment, it is often too advanced for curative measures. Low-dose computed tomography (CT) screening has been shown to reduce mortality in patients at high risk of lung cancer. We present a 66-year-old man with a 50-pack-year smoking history who had a right upper lobe (RUL) pulmonary nodule and left lower lobe (LLL) consolidation on a screening CT. He reported a weight loss of 45 pounds over 3 months, had recently been hospitalized for hyponatremia, and was notably cachectic. A CT of the chest showed a stable LLL mass-like consolidation and a  mm subsolid lesion in the RUL. Navigational bronchoscopy biopsy of the RUL lesion revealed squamous non–small cell lung cancer (NSCLC). Endobronchial ultrasound-guided transbronchial needle aspiration of the LLL lesion revealed small cell lung cancer (SCLC). The final diagnosis was a right-sided Stage I NSCLC (squamous) and a left-sided limited SCLC. The RUL NSCLC was treated with stereotactic radiation; the LLL SCLC was treated with concurrent chemotherapy and radiation. In patients with multiple lung nodules, a diagnosis of synchronous multiple primary lung cancers (MPLCs) is crucial, as inadvertent upstaging of patients with MPLC (to T3 and/or T4 tumors) can lead to erroneous staging, inaccurate prognosis, and improper treatment. Recent advances in the diagnosis of small pulmonary nodules via navigational bronchoscopy and management of these lesions dramatically affect a patient’s overall prognosis.

  • A Novel Mutation in TSC2 Gene: A 34-Year-Old Female with Pulmonary
           Lymphangioleiomyomatosis with Concomitant Hepatic Lesions

    • Abstract: Tuberous sclerosis complex (TSC) is an autosomal dominant disease resulting from mutation(s) in TSC1 or TSC2 genes. TSC is associated with the formation of hamartomas in the brain, heart, eyes, skin, kidneys, and lymphangioleiomyomatosis (LAM) of the lungs. LAM is almost restricted to women in reproductive age. Different mutations in TSC1 and TSC2 genes have been reported in the literature. Here, we present a female patient with TSC-LAM with a novel mutation in TSC2 gene. The patient also had multiple hepatic angiomyolipomas, which is a relatively less-reported manifestation of the disease. The impact of this mutation on the pattern of disease presentation and response to treatment is not clear yet.

  • Robot-Assisted Thoracoscopic Resection of a Posterior Mediastinal
           Mullerian Cyst

    • Abstract: First described in 2005, the Mullerian derived cyst in the mediastinum is a rare finding with few subsequent reports. We report a case of Mullerian cyst occurring in the mediastinum of a 49-year-old female that was resected by robot-assisted thoracoscopic surgery. To our knowledge, this is the first report of robot-assisted resection of Hattori’s cyst. Histopathologic analysis revealed ciliated Mullerian-type tubal epithelium positive for paired box gene 8 (PAX8), estrogen receptor (ER), and progesterone receptor (PR), confirming Mullerian differentiation. We also review the clinical presentation, pathology, and differential diagnosis of such cysts.

  • Pulmonary Alveolar Proteinosis in Setting of Inhaled Toxin Exposure and
           Chronic Substance Abuse

    • Abstract: Pulmonary alveolar proteinosis (PAP) is a rare lung disorder in which defects in alveolar macrophage maturation or function lead to the accumulation of proteinaceous surfactant in alveolar space, resulting in impaired gas exchange and hypoxemia. PAP is categorized into three types: hereditary, autoimmune, and secondary. We report a case of secondary PAP in a 47-year-old man, whose risk factors include occupational exposure to inhaled toxins, especially aluminum dust, the use of anabolic steroids, and alcohol abuse, which in mice leads to alveolar macrophage dysfunction through a zinc-dependent mechanism that inhibits granulocyte macrophage-colony stimulating factor (GM-CSF) receptor signalling. Although the rarity and vague clinical presentation of PAP can pose diagnostic challenges, clinician awareness of PAP risk factors may facilitate the diagnostic process and lead to more prompt treatment.

  • Use of Extracorporeal Membrane Oxygenation in Postpartum Management of a
           Patient with Pulmonary Arterial Hypertension

    • Abstract: Current guidelines do not recommend pregnancy in patients with pulmonary arterial hypertension (PAH). This is due to the associated high mortality, which both dissuades PAH patients from becoming pregnant and encourages termination of pregnancy due to high maternal mortality risk. As a result, there is a lack of data and, consequently, there are only general guidelines available for management of pregnancy in PAH patients. Additionally, novel therapeutic strategies such as extracorporeal membrane oxygenation (ECMO), although used in the management of nonpregnant PAH patients as a bridge to lung transplantation, have not been used to treat cardiopulmonary collapse in pregnant PAH patients. In an attempt to bridge this paucity of data, we report the successful use of ECMO in resuscitation and management of a pregnant PAH patient who experienced cardiopulmonary collapse following a caesarian section.

  • Seizure and Pulmonary Embolism: A Differential That Can Save a Life

    • Abstract: Seizures is a relatively common presentation with a wide differential diagnosis. However, seizures presenting secondary to underlying pulmonary emboli are rare and, without prompt recognition and management, this easily treatable condition can be potentially fatal. The few available case reports discussing seizures and PE reveal a high mortality rate which underscores the importance of prompt diagnosis. A 38-year-old woman presented to the emergency room having experienced loss of consciousness and a generalized tonic-clonic seizure at home. In the emergency room, her presenting signs and symptoms included tachycardia, worsening dyspnea, mild hypoxemia, and elevated D-dimer. Pertinent history findings revealed she recently received depot hormonal contraceptive treatments. Her initial workup included an EKG which showed sinus tachycardia without evidence of right heart strain. Subsequently a chest CT with angiography revealed massive bilateral pulmonary emboli. DVT studies also revealed a unilateral acute DVT. The patient was promptly started on therapeutic anticoagulation and stabilized. Fortunately, the patient remained symptom-free and eventually was discharged with close follow-up. The goal of this report is to make clinicians more aware of the possibility that seizures, along with the appropriate clinical findings, can be caused by acute PE.

  • A Rare Case of Metastatic Choriocarcinoma of Lung Origin

    • Abstract: Choriocarcinoma is part of the spectrum of gestational trophoblastic disease that occurs in women of reproductive age. Although the most common metastatic site of choriocarcinoma is the lung, primary pulmonary choriocarcinoma is rare. To diagnose primary pulmonary choriocarcinoma, the patient should have no previous gynecologic malignancy, have elevated human chorionic gonadotropin, and have pathological confirmation of the disease excluding gonadal primary site of the tumor. Due to the paucity of data, there are no guidelines for treatment. Prognosis of this malignancy is extremely poor. We report a rare case of metastatic primary lung choriocarcinoma in a 69-year-old postmenopausal woman who was treated with combination of surgery, chemotherapy, and radiation. The patient had a good outcome and is doing well after 1-year follow-up.

  • Pulmonary Neuroendocrine Cell Hyperplasia Associated with Surfactant
           Protein C Gene Mutation

    • Abstract: Familial interstitial lung disease (ILD) is defined as presence of ILD in 2 or more family members. Surfactant protein C (SFTPC) gene mutations are rare, but well-known cause of familial ILD. We reported a 20-year-old male, who was referred for lung transplantation. He was symptomatic at age 3 and underwent surgical lung biopsy at age 6, which revealed a nonspecific interstitial pneumonia (NSIP) pattern. Genetic workup revealed a novel SFTPC mutation in the first intron with a C to A transversion. At age 21, he underwent bilateral lung transplantation. Explanted lung histology suggested NSIP. In addition there was pulmonary neuroendocrine cell (PNEC) hyperplasia and carcinoid tumorlets. His mother had undergone lung transplantation several years earlier, and her explanted lung showed similar pathology. SFTPC mutations are inherited in an autosomal dominant pattern. Various types of ILD have been associated with SFTPC mutation including NSIP, usual interstitial pneumonia (UIP), and desquamative interstitial pneumonia (DIP). PNEC hyperplasia has been described to occur in association with lung inflammation but has not been previously described with familial ILD associated with SFTPC mutation.

  • Daptomycin-Induced Acute Eosinophilic Pneumonia: Late Onset and Quick
           Recovery

    • Abstract: Background. Daptomycin is a cyclic lipopeptide antibiotic that provides great coverage for gram positive cocci. From the early years of daptomycin use, concerns were raised regarding the pulmonary side effects of daptomycin and potential development of acute eosinophilic pneumonia (AEP) secondary to daptomycin therapy. Discussion. AEP could be idiopathic or induced by drugs or toxins. It is a distinct entity from atopic diseases and autoimmune, parasitic, or fungal infections that can also cause pulmonary eosinophilia. Multiple medications are associated with acute eosinophilic pneumonia. Multiple cases of daptomycin-induced AEP have been reported in the literature. Diagnosis of AEP is based on clinical history, laboratory tests, and radiographic studies. Obtaining bronchoalveolar lavage or lung biopsy is needed to confirm the diagnosis. Timing of the drug use and clinical presentation is crucial in the diagnosis of drug-induced AEP. Discontinuation of the offending drug and systemic corticosteroids are the mainstay treatment with great outcomes and recovery. Conclusion. We present a case of AEP caused by daptomycin, with complete recovery after discontinuation of daptomycin and administration of steroids. The patient had AEP after almost 6 weeks of daptomycin therapy which has never been reported in literature and our patient achieved complete recovery with appropriate management.

  • Purulent Appearing Material in an Endobronchial Ultrasound-Guided
           Transbronchial Needle Aspiration of Mediastinal Lymph Node: A Diagnostic
           Challenge

    • Abstract: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has increasingly been performed for the diagnosis and staging of thoracic malignancies. Findings of a necrotic lymph node raise concern for infectious process and malignancy. A hypoechoic area on ultrasound/EBUS within a lymph node without blood flow is suggestive of pathologies like infections or malignancy. Inspection of the fluid could suggest a diagnosis; clear aspirates usually suggest bronchogenic or mediastinal cysts and purulent material suggests abscesses or necrotic lymph nodes. Growing tumor cells require a blood supply; if the vascular stroma is insufficient due to rapidly growing malignant tumors this could lead to large central areas of ischemic necrosis. Necrotic aspiration of lymph nodes is not always of infectious etiology. Aspiration of fluid in EBUS-TBNA is a rare occurrence, and malignancy should be considered when purulent fluid material is obtained. We present an elderly woman who underwent bronchoscopy with EBUS-TBNA for evaluation of upper lung nodule and mediastinal lymphadenopathy. Pus-like material was obtained on needle aspiration and endobronchial biopsy and mediastinal core biopsy revealed squamous cell carcinoma.

  • Hemoptysis following Talc Pleurodesis in a Pneumothorax Patient

    • Abstract: The purpose of this article is to report a case of hemoptysis occurring in combination with secondary spontaneous pneumothorax following chemical pleurodesis by talc. A Japanese male with cancer of renal pelvis was found with the left pneumothorax and multiple lung metastases. A computed-tomography scan revealed severe emphysema throughout the lungs. Talc pleurodesis was employed to arrest air leakage. The patient developed hemoptysis 45 minutes after talc injection into the thorax. This is the first report of hemoptysis following talc pleurodesis. The agent could induce severe inflammation in capillary vessels of the lung following visceral pleura infiltration.

  • Symptomatic Patent Foramen Ovale with Hemidiaphragm Paralysis

    • Abstract: Dyspnea accounts for more than one-fourth of the hospital admissions from Emergency Department. Chronic conditions such as Chronic Obstructive Pulmonary Disease, Congestive Heart Failure, and Asthma are being common etiologies. Less common etiologies include conditions such as valvular heart disease, pulmonary embolism, and right-to-left shunt (RLS) from patent foramen ovale (PFO). PFO is present in estimated 20–30% of the population, mostly a benign condition. RLS via PFO usually occurs when right atrium pressure exceeds left atrium pressure. RLS can also occur in absence of higher right atrium pressure. We report one such case that highlights the importance of high clinical suspicion, thorough evaluation, and percutaneous closure of the PFO leading to significant improvement in the symptoms.

  • Multifocal Pulmonary Granular Cell Tumor Presenting with Postobstructive
           Pneumonia

    • Abstract: Granular cell tumor (GCT) is a neoplasm of Schwann cell origin. Its presence in the aerodigestive tract is uncommon and becomes a diagnostic challenge on initial presentation. Our case is of a 59-year-old woman who presented to the emergency department with a history of productive cough and dyspnea associated with fever and chest pain. An initial chest X-ray (CXR) showed a right middle lobe consolidation with follow-up Computed Tomography (CT) scan showing a mass in the right bronchus. Bronchoscopy revealed a polypoid, sessile granular mass in the right bronchus intermedius with multiple white lesions in trachea, left main bronchus, and right upper bronchi. Histology revealed a benign GCT. Bronchoalveolar lavage from the right middle lobe grew Streptococcus pneumoniae. Patient was treated with intravenous levofloxacin during hospital stay and discharged on a 7-day course of oral antibiotics to be followed as outpatient but was lost to follow-up. GCT can present as a polypoid tumor causing recurrent postobstructive pneumonia. Surgical resection is the most successful treatment option. The tumor is more common in third and fourth decade of life and our patient is the oldest patient, according to our knowledge, to have a GCT.

  • Orthodeoxia without Platypnea in Hereditary Hemorrhagic Telangiectasia in
           the Presence of a Cerebral Abscess and Multiple Pulmonary Arteriovenous
           Malformations: Unusual Complications and Transcatheter Endovascular
           Treatment

    • Abstract: Hereditary hemorrhagic telangiectasia is a rare autosomal-dominant condition affecting visceral blood vessel development. Cerebral and most commonly pulmonary arteriovenous malformations are found in the majority of symptomatic patients. The most common complications include embolic strokes and cerebral abscesses, which have been attributed to abnormal vessel communications. Platypnea orthodeoxia is a rare condition that presents dyspnea and oxygen desaturation when adopting an upright position and is relieved on decubitus. The association between hereditary hemorrhagic telangiectasia, pulmonary arteriovenous malformations, and platypnea orthodeoxia has been described in medical literature; however, orthodeoxia as a single entity without platypnea has not been described yet, especially associated with complications of this hereditary condition. We present the case of a 38-year-old male with persistent headaches, in whom a cerebral lesion was detected. Orthostatic tachycardia and severe orthodeoxia without platypnea were evidenced during physical examination. The patient was subsequently diagnosed with hereditary hemorrhagic telangiectasia and underwent cerebral abscess drainage as well as transcatheter endovascular closure of multiple pulmonary arteriovenous malformations. For this reason, the concept of platypnea orthodeoxia syndrome needs further revision. Patients presenting refractory hypoxemia should warn physicians to initially evaluate their oxygen saturation measurements during standing and decubitus position, even though platypnea may not be present.

  • A Rare Case of Idiopathic Plastic Bronchitis

    • Abstract: Plastic bronchitis is a rare disorder characterized by formation of large, branching bronchial casts, which are often expectorated. We present an interesting case of a 35-year-old woman who presented for evaluation of a chronic cough productive of voluminous secretions. Clinical and radiological examination confirmed a total left lung atelectasis without any pathological mediastinal node. Flexible bronchoscopy demonstrated tenacious, thick, and sticky whitish secretions blocking the left stem bronchus. This material was extracted, and inspection demonstrated a bronchial cast, whose pathological analysis revealed necrotic epithelial cells, some eosinophils, and Charcot-Leyden crystals. Two days after bronchoscopy, the patient rejected more bronchial casts, and dyspnea improved. Control of chest x-ray revealed complete left lung aeration and the diagnosis of idiopathic plastic bronchitis was obtained. This article shows the interest in clinical practice to evoke the diagnosis of plastic bronchitis in front of a productive chronic cough. Our case illustrates a rare clinical presentation represented by an atelectasis of an entire lung.

  • Rare Congenital Aberrant Left Superior Pulmonary Vein Discovered with
           Central Line Placement in a Patient with Critical Cardiorespiratory
           Collapse

    • Abstract: Background. Partial anomalous pulmonary venous connection is a rare congenital vascular disorder that may be asymptomatic. Left-sided connections with the innominate vein are discovered infrequently and those without an atrial septal defect are extremely rare. Case. A 66-year-old male was found to have an anomalous left pulmonary vein when a central venous catheter was inserted for management of hypoxemia. In addition to the connection with the left innominate vein an echocardiogram revealed no atrial septal defect. Computed tomography arteriography was used to define the anomaly. Conclusion. Left superior vein partial anomalous pulmonary venous connection with the left innominate vein was discovered incidentally on insertion of central venous catheter. The otherwise innocuous anomaly can become a significant variable when treating critical cardiopulmonary collapse.

  • Acute Low-Dose Hydralazine-Induced Lupus Pneumonitis

    • Abstract: A 35-year-old female was started on hydralazine 10 mg orally three times a day for treatment of postpartum hypertension. Three months later, after multiple unsuccessful courses of prednisone and antibiotics for presumed pneumonia and asthma exacerbations, her respiratory symptoms progressed in severity and she developed resting hypoxia. Previous diagnostic work-up included spirometry with a restrictive pattern, chest CT showing bilateral basilar consolidation, negative BAL, and nonspecific findings on lung biopsy of mild inflammatory cells. Review of systems was positive for arthralgia, lymphadenopathy, paresthesia, and fatigue that began four weeks after starting hydralazine. A clinical diagnosis of hydralazine-induced lupus (HIL) with pneumonitis was made. Antihistone antibodies were positive supporting a diagnosis of HIL. Management included cessation of hydralazine and a prolonged steroid taper. Within days, patient began improving symptomatically. Six weeks later, CT chest showed complete resolution of infiltrates. Genetic testing revealed she was heterozygous for N-acetyltransferase 2 (intermediate acetylator). Drug-induced lupus should be considered in patients with lupus-like symptoms taking medications with a known association. While the majority of HIL cases occur with high doses and prolonged treatment, cases of low-dose HIL have been reported in patients who are slow acetylators.

  • Primary Pulmonary Lymphoma Presenting with Superior Vena Cava Syndrome in
           a Young Female

    • Abstract: Primary Pulmonary Diffuse Large B Cell Lymphoma (PPDLBCL) is an extremely rare entity, which exhibits an aggressive behavior by compressing local blood vessels. It represents only 0.04% of all lymphoma cases and is extremely rare in young age. We present a case of a primary pulmonary lymphoma with superior vena cava syndrome (SVCS) in a young female. 27-year-old African American female presented with fever, cough, and facial puffiness for 2 weeks and unintentional weight loss. Chest examination showed decreased breath sounds and dullness on percussion on right side. Labs were normal except for mild leukocytosis, high lactate, and lactate dehydrogenase. Chest X-ray showed a large right side infiltrate with pleural effusion but chest CT showed 10 × 14 × 16 cm mass in the right lung without hilar and mediastinal lymphadenopathy. CT guided biopsy of the right lung mass was done and large B cell lymphoma was diagnosed. She received “involved field radiation” because of the bulky tumor size and superior vena cava involvement prior to R-CHOP to which she responded well. PPDLBCL should be considered as one of the differentials in a young patient with a large lung mass, which needs timely diagnosis and management.

  • Arterial Thoracic Outlet Syndrome Treated Successfully with Totally
           Endoscopic First Rib Resection

    • Abstract: Thoracic outlet syndrome (TOS) is a constellation of signs and symptoms caused by compression of the neurovascular structures in the thoracic outlet. TOS may be classified as either neurogenic TOS (NTOS) or vascular TOS: venous TOS (VTOS) or arterial TOS (ATOS), depending on the specific structure being affected. The basis for the surgical treatment of TOS is resection of the first rib, and it may be combined with scalenectomy or cervical rib resection. Herein, we describe a case of arterial thoracic outlet syndrome which was successfully treated with totally endoscopic video-assisted thoracoscopic surgery (VATS) first rib resection.

    • Abstract: Hemothorax is a rare but potentially fatal postthoracentesis complication. Early clinical signs may be nonspecific resulting in diagnostic delay. A high index of suspicion is vital for early diagnosis and intervention to avoid further bleeding. Following procedure, early bedside ultrasound findings can be vital for early detection. We report a case of massive hemothorax in a 63-year-old male following therapeutic thoracentesis. Diagnosis was made following highly suggestive sonographic findings prompting thoracotomy and lacerated intercostal artery cauterization.

  • An Unusual Presentation of Congenital Lobar Emphysema

    • Abstract: Congenital lobar emphysema is an uncommon bronchopulmonary malformation characterized by lobar overinflation and accompanying alveolar septum damage that leads to compression atelectasis of the lung parenchyma and displacement of mediastinal structures, with the resultant ventilation-perfusion mismatch. We present a case of a 33-year-old lady with progressive exertional dyspnea. Chest radiograph findings lead to the suspicion of congenital lobar emphysema, which was then confirmed by a computed tomography (CT) scan. This condition is most commonly identified in newborns, with very few cases being reported in adults. Lobectomy remains the treatment of choice and in general has good outcome.

    • Abstract: Bronchus Associated Lymphoid Tissue Lymphoma (BALTOMA) is a rare subgroup of pulmonary non-Hodgkin’s lymphomas (NHLs) comprising less than 1% of all cases. It constitutes 3.6% of all extranodal lymphomas and only 0.5–1% of primary pulmonary malignancies. They are usually low grade B-cell lymphomas and are considered to originate from the mucosa associated lymphoid tissue (MALT) of the bronchi. Here, we represent a rare case of BALTOMA presenting with immunodeficiency and multiple pulmonary nodules.

           Postextubation Stridor

    • Abstract: Postextubation stridor is associated with significant morbidity. It commonly results in extubation failure after established medical treatment fails, such as nebulized epinephrine and/or intravenous steroids. The role of heliox (i.e., combination of helium and oxygen) in managing patients with postextubation stridor has not been fully established. We report two cases of postextubation stridor successfully treated with heliox delivered with bilevel positive airway pressure (BiPAP) after failure of standard medical therapy.

  • A Rare Presentation of Sarcoidosis as a Pancreatic Head Mass

    • Abstract: Sarcoidosis is a multisystem granulomatous syndrome of unknown etiology with noncaseating epithelioid granulomas being the pathognomonic pathological finding. Sarcoidosis most commonly involves the lungs and involvement of the gastrointestinal (GI) tract is uncommon. Pancreatic sarcoidosis is very rare, especially when it is the presenting feature of sarcoidosis and can masquerade as pancreatic cancer. Tissue infiltration in pancreatic sarcoidosis can lead to either a diffuse nodular appearance or a mass-like lesion. We present an interesting case of a 47-year-old woman with a 10-pack-year history of smoking who presented with sharp epigastric pain, weight loss, and elevated lipase level. CT and MRI imaging showed a 4 cm × 5 cm heterogeneous pancreatic mass with a dilated pancreatic duct and peripancreatic lymphadenopathy. Endoscopic ultrasound guided FNA revealed noncaseating granulomas with no evidence of malignancy or atypical infection. CT of the chest revealed bilateral mediastinal and hilar adenopathy with calcification, without any parenchymal abnormalities, and her angiotensin-converting enzyme level was elevated at 170 U/L. The clinical picture pointed to the diagnosis of pancreatic sarcoidosis. Given the severity of gastrointestinal symptoms related to pancreatic sarcoidosis, prednisone therapy at 0.5 mg/kg/day was initiated with complete resolution of symptoms at 8 weeks.

  • Postpneumonectomy Compression of the Mitral Annulus: Rare Vascular
           Complication in Sportive Patient

    • Abstract: Numerous postpneumonectomy complications exist. We present a rare clinical case of postpneumonectomy exertional dyspnea revealing compression of the mitral annulus by the descending aorta. The patient was 42-year-old former smoker with pulmonary emphysema. He has been operated on, in 2012 (i.e., right pneumonectomy). Before the surgery, the patient was a recreational runner. However, after some months, it was difficult for the patient to resume running. Cardiopulmonary exercise testing indicated moderate exercise intolerance with important oxygen desaturation. More interestingly, a decrease of low oxygen pulse was noticed from the first ventilatory threshold with no electrical modification on the electrocardiogram. This decrease was indicative of a decline in stroke volume. The thoracic scan revealed a right pneumonectomy pocket with a liquid abnormal content. Moreover, the mediastinum had shifted toward the pneumonectomy space and the left lung was distended and emphysematous. Echocardiography revealed a major change in the mediastinal anatomy. The mitral annulus was observed to be compressed by the rear wall of the descending aorta. The diagnosis of postpneumonectomy syndrome or platypnea-orthodeoxia syndrome was ruled out in this patient. Mitral annular compression by the descending aorta is rare complication, which must be researched in patients with postpneumonectomy exertional dyspnea.

  • Extracorporeal Lung Support as a Bridge to Diagnosis of Pulmonary Tumor
           Embolism

    • Abstract: Bridging to diagnosis is an emerging technique used in end-stage cardiorespiratory failure that prolongs a patient’s life using various modalities of extracorporeal lung support (ECLS) to achieve antemortem diagnosis. Pulmonary tumor embolism occurs when cell clusters travel from primary malignancies through venous circulation to the lungs, causing respiratory failure through inflammatory and venoocclusive pathways. Due to its nonspecific symptomatology, pulmonary tumor embolism remains an elusive diagnosis antemortem. Herein, we bridge a patient who presented in acute respiratory failure to the diagnosis of pulmonary tumor embolism from a gastric signet-ring cell carcinoma using ECLS modalities including venoarterial extracorporeal membrane oxygenation and centrally cannulated Novalung pumpless extracorporeal lung assist. We demonstrate the utility of this approach in diagnostically uncertain cases in unstable patients who are potentially acceptable ECLS and transplant candidates.
