  • Review of surgical anatomy of the tumors involving cavernous sinus

    • Authors: Silky Chotai, Yi Liu, Songtao Qi
      Pages: 1 - 8
      Abstract: Silky Chotai, Yi Liu, Songtao Qi
      Asian Journal of Neurosurgery 2018 13(1):1-8
      The lesions involving cavernous sinus (CS) and lateral sellar region includes tumors, vascular lesions, infection, inflammation, and trauma. Tumors associated with CS cause significant distortion of the microanatomy posing an additional surgical challenge to the neurosurgeons. The surgical approach and microsurgical anatomy with respect to the origin and growth of the tumor within the CS region have not been comprehensively described in recent years. We conducted a review of literature concerning CS and associated tumors, complied through MEDLINE/OVID and using cross-references of articles on PubMed with the keywords cavernous sinus, CS tumors, pituitary adenoma, meningioma, schwannoma, chordoma, CS hemangiomas, extradural, interdural, intradural, skull base, gamma knife radiosurgery, endoscopic endonasal approach. Based on the tumor origin and growth pattern, the tumors associated with CS can be classified into three categories: Type-I: tumor originating from CS, Type-II: originating from lateral wall of CS, and Type-III: extraneous origin and occupying CS. The review focuses on approach to a tumor within each type of tumor in the CS region. The emphasis is that the tumor growth pattern and significant distortion of the CS anatomy caused by the tumor growth should be considered while planning the optimal surgical approach for tumors in this region to ensure complete tumor resection with minimal neurovascular morbidity.

      Abstract: Sengottuvel Thanapal, Shyam Duvuru, Treepob Sae-Ngow, Yoko Kato, Katsumi Takizawa
      Asian Journal of Neurosurgery 2018 13(1):9-17
      In 1967, the first extracranial to intracranial (EC-IC) arterial anastomosis was performed. Since that time, EC-IC bypass surgery has become a widely accepted surgical treatment for patients with IC stenotic or occlusive atherosclerotic lesions. This article will discuss the history, indications, types, surgical methods, and complications of the EC-IC bypass.

  • Is mechanical ventilation mandatory for the management of severe head
           injury? outcome in 53 medically managed severe head injury patients,
           without ventilatory support: A prospective study

      Abstract: Ponraj Kamatchi Sundaram, Pankaj Arora, Jinendrakumar Ramalingam, Jorson D'Costa
      Asian Journal of Neurosurgery 2018 13(1):18-22
      Background: Severe head injury (SHI) is a major cause of mortality and morbidity across the world. The current paradigm of management of SHI involves admission in Intensive Care Unit (ICU), mechanical ventilation (MV), and intracranial pressure (ICP) monitoring. Such resources are expensive and often unavailable in the developing world. Objective: MV or ICP monitoring was unavailable for our patients due to the scarcity of resources. Hence, other alternatives were considered to prevent secondary brain injury due to hypoxia. This study assessed the outcome after SHI when managed with an early tracheostomy (ET). Methods: This prospective observational study over 13 months included all medically managed SHI patients without MV or ICP monitoring. The Glasgow outcome scale (GOS) was assessed at discharge and compared with published historical data reported after treatment in an ICU environment. Results: Our study included 53 unoperated patients with SHI among 1862 patients with traumatic brain injury. Overall mortality was 24.5% (13/53) and compared favorably with reported mortality of 25%–40% reported from centers using intensive management. At discharge, the favorable outcome with a GOS of 4 or 5 was seen in 39.6% (21/53). Conclusion: With ET, the results of management of SHI in our patients were comparable to results reported after MV in an ICU environment. Hence, ET is a cost-effective alternative when resources are scarce. MV should be used if hypoxia persists after tracheostomy. Although MV effectively prevents hypoxia, it has complications. We conclude that although MV was unavailable for our patients, they did not have the complications associated with it.

  • Cerebral contusion: An investigation of etiology, risk factors, related
           diagnoses, and the surgical management at a major government hospital in
           Cambodia

    • Authors: Louise Vera Hilmer, Kee Bum Park, Iv Vycheth, Michael Wirsching

      Abstract: Louise Vera Hilmer, Kee Bum Park, Iv Vycheth, Michael Wirsching

      Introduction: Cerebral contusions are a common type of injury among the Cambodian population, mostly due to road traffic accidents. This article aims to assess various aspects around brain contusion focusing on the condition at admission, residing province, mechanism and time of injury, age and sex distribution with differing helmet wearing, and alcohol consumption patterns. Hospitalization-related data such as treatment and outcome were analyzed. Methods: This was a retrospective analysis of 406 cases who have been admitted during the period between May 2013 and May 2016. Results: Two hundred and ninety-five (75.51%) of the patients came from rural areas, 312 (76.84%) were male (mean age 31.17 ± 12.90 years for males and 38.5 ± 16.29 years for females). The average hospital stay amounted to 10.51 ± 6.67 days. One hundred and eight two cases (52.29%) happened between 4.00 and 11.00 p.m. Three hundred and nineteen (79%) of the injured patients were motorcycle drivers and 18% pedestrians. Male patients had an alcohol involvement in 135 (49.45%) (females in 5 [6.25%]) cases and 26 (10%) wore a helmet (females in 5 [6.25%]). Surgery was performed in 82 cases, specifically craniotomy and craniectomy +/− elevation of a depressed skull fracture. Two hundred and ninety-six (73.09%) patients showed related second diagnosis, mostly subdural hematoma in 96 (32.43%) and epidural hematoma in 63 (21.28%) cases. Fifty patients (13.16%) had a Glasgow Coma Scale of 3–8. 92 (24.21%) of 9–12 and 238 (62.63%) of 13–15 on admission. Most of the patients were discharged with an improved status 324 (91.52%) according to the Glasgow Outcome Scale 4 or 5. Conclusion: The severity and resulting neurologic impairment of cerebral contusions show the importance of more in-depth research and prevention programs.

  • The effect of hand exercise on reducing the symptoms in hemodialysis
           patients with carpal tunnel syndrome

    • Authors: Seher Unver, Neriman Akyolcu
      Pages: 31 - 36
      Abstract: Seher Unver, Neriman Akyolcu
      Asian Journal of Neurosurgery 2018 13(1):31-36
      Context: Carpal tunnel syndrome (CTS) is one of the most common peripheral neuropathies, and there is no consensus on the preferred method of treatment. Aims: The aim of this study is to determine the effects of hand exercise performed with a ball on symptoms and to evaluate the results in hemodialysis (HD) patients with CTS. Settings and Design: This study was conducted in patients with HD who were treated in dialysis centers and state hospitals in Turkey between 2011 and 2012. Subjects and Methods: This study included 19 patients (28 hands) that were diagnosed as CTS. For exercise treatment, a hand and finger exercise ball that consists of two parts: a foam body and flexible rubber cords was used. Patients placed their fingers through each cord, squeezed it for 1 s, and then opened their fingers against the cord for 1 s. Patients repeated this exercise for 30 s to 1 min/day. Statistical Analysis Used: The McNemar, Friedman ANOVA, and the Wilcoxon test with a Bonferroni correction were used on SPSS 20.0 software package program. P < 0.05 was considered statistically significant. Results: Results showed that recovery was performed from physical examination results, grip strength, and Boston questionnaire scores. About 21.4% of patients' electrophysiological results were negative at the end of the 1st month and 32.1% of them at the end of the 3rd month. Conclusion: Due to the slowed progress of CTS and detection of slight improvement in evaluation parameters, this self-applicable and practical exercise can be used as an alternative treatment of mild CTS in patients with HD.

      Background: The aim of our study is to assess the neuroprotective effects of the tumor necrosis factor alpha (TNF-α) inhibitor etanercept (ETA) on histopathological and biochemical changes following spinal cord injury (SCI). Patients and Methods: Fifty-four male Wistar albino rats were randomly assigned into three main groups: The sham, trauma, and ETA group (n = 18 per group). Each of these groups was further divided into three subgroups (n = 6 per subgroup) based on the different tissue sampling times postinjury: 1 h, 6 h, and 24 h. Clip compression model was used for SCI. Rats in the ETA group were treated with 5 mg/kg of ETA immediately after the clip was removed. After 1, 6, and 24 h, the spinal cord was totally removed between the levels T8–T10. Sample tissue was immediately harvested and fixed for histopathological and electron microscopic examination and were analyzed for TNF-α, interleukin-1β (IL-1β), superoxide dismutase (SOD), adenosine deaminase, catalase (CAT), and malondialdehyde levels in both the tissue and serum. Results: The serum and tissue levels of cytokines and enzymes were seen to change after SCI between hyperacute, acute, and subacute stages. Treatment with ETA selectively inhibited TNF-α, and IL-1β expression together with increased levels of antioxidative enzymes (SOD, CAT). Conclusion: Early administration of ETA after SCI may remarkably attenuate neuronal injury by decreasing tissue and serum TNF-α and IL-1β levels, while increasing antioxidative enzymes such as SOD and CAT in subacute and acute stages, respectively.

      Introduction: We aimed to assess the effect of anti-tyrosine kinase inhibitors (TKIs) (gefitinib) in overall survival (OS) of the glioblastoma multiforme (GBM) patients in the backdrop of mutational status of epidermal growth factor receptor (EGFR) and PTEN genes. Materials and Methods: All the patients subjected to resection or biopsies were put on gefitinib, and radiotherapy was delivered as per the hospital protocol. EGFR and PTEN mutational spectrum was performed by single-strand conformation polymorphism followed by DNA sequencing. Results: In total, 50% GBM tumors had mutation either in EGFR or PTEN. Median progression-free survival (PFS) and OS observed in patients with EGFR +ve/PTEN −ve were significantly favorable (P < 0.05) which aggregated to 9(7, 11) months and 20 (16, 24) months, respectively, than 6 (4, 8) months and 13 (7, 19) months in patients with PTEN +ve/EGFR −ve. Patients positive for both EGFR/PTEN had lower disease-free survival and OS of 6 and 9 months as compared to 6 (5, 7) and 14 (12, 24) months for those negative for both EGFR/PTEN. Conclusions: We conclude that EGFR gene alterations with wild-type PTEN are associated with significantly better PFS and OS in patients treated with anti-TKIs (gefitinib). Combined EGFR and PTEN gene mutation is associated with significantly poor response to gefitinib in terms of median OS.

      Aneurysms arising from anterior inferior cerebellar artery-posterior inferior cerebellar artery (AICA-PICA) variant are extremely rare. They usually present with subarachnoid hemorrhage. This is probably the second case report of a large thrombosed AICA-PICA variant aneurysm presenting as a cerebellopontine angle mass lesion with cranial nerve palsy, managed successfully by surgical clipping.

      Dengue fever has been a major cause of morbidity and mortality in subtropical and tropical countries. We report a rare case of severe dengue with spontaneous intracranial hemorrhage. A search of literature through PubMed revealed that the largest series analyzed so far only included five cases. A 47-year-old man presented with 7 days history of fever, headache, myalgia, and vomiting with hematemesis. On the day of presentation, he had reduced consciousness and an episode of generalized tonic-clonic seizure. His Glasgow Coma Scale was E1V1M3 with anisocoria. Postresuscitation computed tomography of the brain revealed a right subdural and left thalamic hemorrhage. His blood investigations revealed thrombocytopenia, dengue virus type 1 nonstructural protein antigen test was positive, dengue IgM negative, and dengue IgG positive. A right decompressive craniectomy was done. Unfortunately, the patient died soon after. Spontaneous intracranial hemorrhage in patients with dengue fever is an uncommon entity but usually carry a grave prognosis. To date, there has been no clear management guideline for such cases, as both operative and nonoperative approaches have their own inherent risks.

      Scalp arteriovenous malformations (AVMs) are abnormal vascular lesions that can be treated safely and effectively, with surgical or endovascular approaches. Because of their complex vascularity, the detailed preoperative evaluation must be carefully performed. Here, we present a case of scalp AVM that required two operations as a result of a misdiagnosis because of inadequate preoperative assessment.

      Craniopharyngiomas usually involve the sella and suprasellar space. Their occurrence in the posterior fossa without extension to the suprasellar region is uncommon with only 16 cases reported in the literature. We report a case of a primary posterior fossa craniopharyngioma that was managed by complete excision with a good recovery. Our case was unique in that the craniopharyngioma occurred in the fourth ventricle and extended downward to the level of C1, a manifestation that was reported only twice in the past. The literature on the topic is reviewed.

      Chondrosarcoma is the second most common primary malignancy of bone after osteosarcoma. Cranial primary chondrosarcomas mostly originate from the skull base cartilage formation zones. Parasagittal falcine origin is very rare for primary extra-skeletal intracranial chondrosarcomas. We report a rare case of primary myxoid chondrosarcoma at falx cerebri. The patient was a 35-year-old lady with right arm and leg weakness. Her brain magnetic resonance imaging depicted a left parasagittal mass lesion attached to the falx cerebri. En bloc resection via left frontal craniotomy was performed. Three more local recurrences occurred in 9 months' time since the index surgery, which were all managed with re-surgeries and/or adjuvant stereotactic radiosurgeries. This is the second case of myxoid type parasagittal chondrosarcoma but with the most protracted disease course. Even though surgery remains the mainstay of treatment for parasagittal chondrosarcomas, adjuvant therapy might be necessary in aggressive ones.

      Tethering of the spinal cord in the lumbosacral region with myelomeningocele is a well-known phenomenon. Only sporadic cases of tethering along the rest of the neuraxis, including the hindbrain, cervical, and thoracic spinal cord have been documented, always along with some associated congenital malformations (hydrocephalus, Chiari malformation, myelomeningocele, meningocele, hamartomatous stalk, spina bifida occulta, intramedullary lipoma, intradural fibrous adhesions, the fusion of the sixth and seventh cervical vertebrae, split cord malformation, or low-lying cord). In this report, 14-year-old male developed symptoms related to tethering of the cervical spinal cord, but without any associated congenital malformations, that is the pure tethered cervical cord. This causes his moribund status and makes the manuscript unique and contributes to the hitherto literature. The authors discuss the diagnosis, treatment, and postoperative course of this entity. The uniqueness in treatment is that we have operated the case without the help of intraoperative somatosensory evoked potentials and motor evoked potential from posterolateral approach under local anesthesia.

      Tracheal intubation is performed as part of daily routine in the operating room, rarely with complications. However, management of airway for cases such as a penetrating neck trauma case might constitute exceptions, in which cases the stabilization of the neck to prevent any further neural damage is a significant source of concern for the anesthesiologist. Generally, intubation techniques for penetrating neck trauma were planned according to the initial position of patients. To our knowledge, this is the first case report of alterated the position of the patient during the anesthesia induction for direct laryngoscopy. We report a case of successful airway management of a patient with penetrating neck trauma, by endotracheal intubation with direct laryngoscopy (DL) technique.

      Herpes encephalitis superimposed on an intracranial malignancy has previously been described mainly in the context of malignancy imitating infection or in the postoperative setting after neurosurgical intervention. We report a rare case of de novo presentation of concurrent herpes encephalitis and glioblastoma. A 63-year-old man presented with status epilepticus and subsequent magnetic resonance imaging (MRI) brain showed a right temporal enhancing lesion with mass effect. He underwent a craniotomy and debulking of this lesion, which on subsequent histology was positive for herpes simplex virus (HSV) antigens and HSV DNA was confirmed by polymerase chain reaction analysis. The sample however also had some hypercellular areas with atypical astrocytes. Our patient recovered well from surgery and was eventually commenced on acyclovir albeit with a delay of 3 weeks due to the initial diagnostic dilemma. However, he re-presented with lethargy and confusion a further 3 weeks later and an MRI scan showed recurrence of the temporal lesion with MR spectroscopy more suggestive of high-grade glioma. He, therefore, underwent a further debulking surgery and the histology revealed a WHO Grade 4 glioblastoma with some residual areas of inflammation. A diagnosis of 2 co-existing pathologies namely HSV encephalitis and glioblastoma was thus reached. Unfortunately, due to poor performance status, he could not undergo chemo-radiotherapy and died 8 months after presentation. Immuno-modulators, expressed locally and globally in glioma patients, are likely to render them susceptible to infections. There are an increasing number of reports of HSV encephalitis in the glioma setting postoperatively. However, we report a de novo presentation which has only been recognized once before in the 1970s. Recognition of HSV encephalitis in glioma patients in the de novo and also the postoperative context is important for commencing early treatment and preventing poor outcomes.

      Lipomas and lipoblastomas are benign tumors of mesenchymal origin in contrast to liposarcoma that is a malignant tumor. Atypical lipomatous lesion arising from embryonal fat cells is termed as lipoblastoma. In the present case report 9-month-old male presented to us with painless, rapidly progressing mass over back, power was normal in all four limbs, fine needle aspiration cytology was suggestive of cellular tissue, magnetic resonance imaging suggestive of well-defined enhancing mass in paravertebral location, extending from D3 to D10 vertebrae with intraspinal extension, communicating through neural foramina at level of D7. Intraoperatively, it was dumbbell-shaped, looked like neurofiboma based on the gross findings and it was adherent to dorsal nerve root also. Single level laminectomy with complete surgical excision of lesion done with sacrifice of dorsal nerve root. Histopathology was suggestive of lipoblastoma. Postoperative recovery was uneventful.

      The most common benign tumor of the brain is meningiomas. Usually diagnosed between the ages of 40–60, they are more common in women. Studies have shown a strong relationship between hormones and malignancies. Although meningiomas are slow-growing tumors of the brain, pregnancy seems to induce its growth speed. Studies concerning meningiomas and hormone relationship may explain the reason why symptoms during pregnancy flare. More specifically, the estrogen and progesterone receptor may take an active role through signal transduction in inducing the growth of the tumor. Thus, the dilemma of pregnancy + meningioma arises. In this case, a 21-year-old pregnant with a giant meningioma diagnosed on the symptom of loss of sight is reported. Her pregnancy was terminated, and the tumor was excised. Her vision improved and the histopathological examination showed a progesterone receptor positive meningioma. It is a challenging decision to be made by the physician, the patient and the family when deciding if and when pregnancy should be terminated once an intracranial meningioma is diagnosed.

      The Fahr syndrome (FS) is a rare degenerative neurological disorder (its prevalence is <0.5%). FS is distinguished by the presence of abnormal bilateral intracranial calcifications with a predilection for the basal ganglia, also presented by movement disorders such as parkinsonism, paresis, and speech disorders. Chronic subdural hematoma (CSH), which is typically the result of mild head trauma, is a regularly encountered condition in elderly. A 63-year-old man has referred to our clinic from another hospital with a history of mild head trauma approximately a month ago. At the time of admission, the patient's Glasgow Coma Scale point was 15 points. In the history, there was only mild ataxia and right-sided hemiparesis. The laboratory examination revealed no electrolytes level abnormalities and normal endocrinal test examinations. Computed tomography revealed bilateral calcifications of basal ganglia, dentate nuclei which were misinterpreted as intracerebral contusion; with CSH of left temporal and parietal region. The hematoma was evacuated by burr-hole drainage. The patient was discharged 5 days after the surgery. The pathophysiology of FS is still unrevealed. There are some suggestions such as secondary to local disturbance of blood-brain barrier or a calcium neuronal metabolism disorder. However, on the other hand, local blood-brain barrier disturbance would also take part in CSH pathology. We hypostasized that patients with the history of FS, who had mild head traumas, might prone to subdural collections. On the other hand, FS and CSH coexistence is very unusual. Neurosurgeons might keep in mind FS when bilateral calcifications are seen in a patient.

      Pituitary apoplexy is a rare clinical presentation caused by infarction of the pituitary gland or adenoma with or without hemorrhage. Although pituitary apoplexy is usually spontaneous, one of the predisposing factors is treatment with dopamine agonists, especially bromocriptine. The occurrence of apoplexy during cabergoline therapy is reported much less frequently. In this article, we report a 34-year-old man with macroprolactinomas who developed sudden visual deterioration due to pituitary apoplexy 1 year after initiation of cabergoline therapy. He was treated via endoscopic trans-sphenoidal surgery and his visual status recovered dramatically.

      Schwannoma is a benign neural tumor derived from Schwann cells surrounding the nerves. It occurs primarily in subcutaneous tissues and muscles with a tendency for distal extremities, head, and neck area. Treatment of schwannoma is surgical excision. Lipomas are the most common soft-tissue lesions. A case is presented to increase awareness on differential diagnosis of head and neck subcutaneous masses.

      Meningiomas account for a significant proportion of all primary intracranial tumors; distant metastasis is quite rare. We report a patient with resected, atypical meningioma. The patient's clinical course over 5 years included two craniotomies, a course of radiation, and a shortened course of bevacizumab. Only 5 months after starting bevacizumab, the patient developed an isolated left clavicular pathological fracture attributable to metastatic anaplastic meningioma. This constitutes the first report of meningioma with isolated extracranial intraosseous metastasis in the modern English literature and highlights concerns associated with the use of anti-angiogenic agents in promoting more invasive tumor phenotypes upon disease recurrence.

      Yawning, a physiologic reflex exhibited by vertebrates, is seldom noticed as a symptom of a disease. Not too often is a patient aware of it as a symptom, unless it is of such a distressing nature to seek attention. In this situation, to distinguish between normal and abnormal behavior would pose a diagnostic dilemma for the attending physician. Intractable yawning has been a presenting symptom of many pathologic states such as stroke, epilepsy, and migraine. Literature is sparse regarding intractable yawning caused by tumors of the brain. Most of the time, the etiology cited is the infratentorial location of these tumors causing compression of the brainstem and the centers responsible for yawning. Intractable yawning as a predominant symptom of supratentorial tumor is rare. We present a case of an 18-year-old girl who presented with abnormal yawning. On evaluation, magnetic resonance imaging revealed a tumor in the posterior part of the inferior temporal gyrus. There was no significant compression of the brainstem structures to suggest this as a cause for her symptom. She underwent a craniotomy and total excision of lesion. Postoperatively, her symptoms improved and her salvos of yawns ceased. The histopathological examination revealed a ganglioglioma of the temporal lobe. The present case is unique as it is the only case reported in the literature of a supratentorial tumor causing abnormal yawning.

      We report a 69-year-old patient with left paresthesia and hemiparesis. Magnetic resonance imaging revealed a right frontoparietal cystic tumor. A subtotal surgical resection was performed, and an Ommaya reservoir was left in place. The pathological diagnosis was supratentorial extraventricular anaplastic ependymoma. Radiation therapy was administered, and Ommaya reservoir drainages were performed. Four months after, her clinical status deteriorated after a reservoir drainage and image revealed an acute hemorrhage. An additional resection was carried out, and chemotherapy was undergone. One month later the tumor relapsed and the patient died 18 months after initial diagnosis. Some poor prognostic factors have been suggested in the literature: Young age, incomplete tumor resection – eloquent area location, histological anaplasia, supratentorial, and extraventricular locations. Ommaya reservoirs may be used in cystic lesions as a temporary measure only. Surgery is the mainstay of therapy with adjuvant radiotherapy and/or chemotherapy.

      Primary cutaneous meningioma of scalp is a rare lesion and often clinically misdiagnosed. As clinical features are nonspecific, the diagnosis is often perplexing in this exceptional site. We report a case of a 7-year-old girl presenting with a nodule over occipital region of scalp since birth. No bony defect was noted on X-ray. On fine needle aspiration cytology, smears were cellular consisting mostly cohesive clusters of cells having pale pink granular cytoplasm, round to oval nuclei with unassuming nucleoli along with psammomatous calcification suggestive of cutaneous meningioma. Histology and immunohistochemistry with epithelial membrane antigen (EMA) confirmed the diagnosis. Histological sections revealed a proliferation of a spindle-shaped cell in the dermis, arranged in whorls or individually amid collagen fibers and psammoma bodies. Immunohistochemical study revealed positivity for EMA. A diagnosis of Type I cutaneous meningioma was finally rendered based on characteristic clinical, intraoperative, morphological, and immunohistochemical observations.

      Mycotic cerebral aneurysms are rare inflammatory aneurysms associated with high mortality and morbidity reaching up to 80% after rupture. We report a case of incidentally diagnosed infective endocarditis presenting with rupture of distal middle cerebral artery mycotic aneurysm and intracerebral hematoma. Aneurysmectomy with clip ligation of the terminal cortical branch and hematoma evacuation was done with good surgical outcome.

      Intracranial arachnoid cysts (ACs) are relatively common findings that can be seen in up to 2% of patients. They are generally found incidentally with a benign clinical course and can be usually managed by observation. We report an unusual case of a middle fossa AC presenting with spontaneous intracystic hemorrhage along with subdural hematoma (SDH) causing significant mass effect and midline shift requiring surgical treatment. Even though the risk of hemorrhage in patients with AC is very low, the presence of AC is a known risk factor for SDH. Fortunately, the clinical outcome of patients who present with hemorrhage associated with AC is generally favorable with early recognition and prompt surgical treatment. Our case highlights the fact that both intracystic hemorrhage and SDH can occur in association with AC even in the absence of trauma and should be kept in mind when counseling patients with incidental AC about the natural history of these lesions.

  • Use of detachable coils without the need of a double marker microcatheter:
           Technical note

      When using detachable coils for cerebral aneurysm embolization, it is necessary to place a microcatheter with radiopaque markers at 2 sites (tip and 3 cm proximal from the tip) in most cases. Detachable coils that can be positioned independently from the proximal marker may facilitate new applications utilizing their characteristics. Herein, we report 2 cases that were treated with new applications. Detachable coils that function to electrically detect the moment they come out of the microcatheter were used. In one patient with a large aneurysm with an irregular shape, coil embolization was applied by advancing the catheter more than 3 cm from the aneurysm neck to the caudally protruded compartment near the proximal end of the neck, which was difficult to reach with the coil. In the other patient with cerebral arteriovenous malformation (AVM), microcatheters for AVM without a proximal marker were used for coil embolization before Onyx injection: Coil embolization was applied through one microcatheter to a site more proximal than the tip of the other microcatheter, followed by Onyx injection through the distal catheter, by which the nidus was continuously penetrated from the initiation of injection, obtaining an effect similar to that of the plug and push technique. Through the use of detachable coils, which are not dependent on the visibility of the proximal marker, the limitation of catheter positioning is reduced and the applicable types of catheter increase, which may facilitate to enable its use for new clinical indications.

      De novo obstructive hydrocephalus is a rare event during pregnancy. There are only case reports presented in literature. We aimed to discuss the pathophysiological basis and management options with an exemplary case presentation and review of the current literature. A 28-year-old G2P1 patient presented to our clinic with headache, vomiting, and deteriorated vision at the 8th week of gestation. She had no history of central nervous system infection or trauma. A brain magnetic resonance imaging was obtained. There was hydrocephalus due to cerebral aqueduct stenosis (Evan's index of 58%). She was managed conservatively with bed rest and diuretics; however, she got no relief. A ventriculoperitoneal shunt was inserted at the 13th week of gestation. At the 38th week, she had cesarean section (C/S) due to previous history of C/S in the first pregnancy and present cord entanglement of the fetus. C/S was conducted under epidural anesthesia after conforming she had no increased intra cranial pressure findings. Delivery was uneventful with a healthy newborn. Obstructive hydrocephalus is a very rare complication during pregnancy. Hydrocephalus becomes obvious and necessitates treatment, before the third trimester of pregnancy. Timely diagnosis, especially differentiation from preeclampsia, is a life-saving step. If no complication happens during intervention for hydrocephalus, spontaneous vaginal delivery is a safe way of delivery for both mother's and newborn's well-being. C/S should be saved for obstetrical indications and can be conducted under epidural anesthesia if intracranial pressure is kept under control. Interdisciplinary approach of neurosurgeons and anesthesiologists is pivotal for delicate care of the patient and the baby.

      Brown-Séquard syndrome, while uncommon, is a neurological condition that classically results from the hemisection of the spinal cord as a result of a penetrating injury to the spinal cord. We present a reported case of blunt trauma causing a high-energy cervical burst fracture/dislocation with a significant cord signal change producing Brown-Séquard syndrome. In this case, the burst fracture at the level of C5 obtained from the motor vehicle accident led to the damage of the left-sided lateral spinal thalamic tract, descending lateral cortical spinal tracts, and ascending dorsal column. This is a unique case of blunt nonpenetrating trauma leading to a high-energy cervical burst fracture/dislocation causing significant cord signal change on T2-weighted magnetic resonance imaging (MRI). These physical changes produced symptoms of neurologic impairment commonly seen in those patients with Brown-Séquard syndrome.

      This is a case report of a 48-year-old man with multiple transient ischemic attacks and a known hypoplastic right vertebral artery (VA) who presented after a syncopal event while turning his head to the left. The objective of this study is to demonstrate the necessity of proper diagnosis and management of cerebrovascular pathology including imaging and surgical intervention in patients with known anatomical anomalies. This study was conducted at Massachusetts, United States of America. Our patient's history was significant for a hypoplastic right VA and a stenotic segment of the right VA at the C3–C4 junction. There was also degeneration of the C3–C4 facet on the left, with osteophyte formation compressing the VA, and a fusion of the C2–C3 segment. Imaging demonstrated obliteration of the left VA flow with head rotation to the left and subsequent reconstitution of flow in the neutral position. After consultation, the patient decided to proceed with surgical management with an anterior cervical discectomy and fusion at the level of C3–C4. Symptoms of vertebrobasilar insufficiency including syncopal episodes resolved after treatment. VA anomalies, although uncommon, are important to understand. Our patient presented with an anomalous right VA, as well as severe degenerative changes to the C2/C3 vertebrae that contributed to the development of Bow Hunter's syndrome. It is essential that proper monitoring and follow-up has to be carried out in patients with abnormal cerebral vasculature to minimize the occurrence of Bow Hunter's syndrome.

      Trigeminal schwannomas (TSs) are extremely rare tumors in childhood, particularly in the absence of neurofibromatosis. Although multi-staged surgical strategies have been reported in the literature, safe and single stage microsurgical removal is possible. We report a rare case of dumbbell TS, in a 9-year-old girl in whom single stage complete removal was done using fronto-temporo-orbito-zygomatic craniotomy and sub temporal approach.

      Teratomas are a type of multipotential cell tumor that contain a mixture of multiple germinal layers formed by normal organogenesis and reproductive tissues the incidence of intracranial teratomas is low, approximately 0.5-2.2% of all intracranial tumors. The occurrence of teratomas in the spine is extremely rare. Except for in the sacrococcygeal region, teratomas constitute <0.5% of all intraspinal tumors. According to the literature this is only 8th case of dorsal spinal mature cystic teratoma reported till date.

      Intracranial malignant peripheral nerve sheath tumors (MPNSTs) are an extremely rare entity with only a handful of cases reported in the literature. MPNSTs typically occur in the extremities and the trunk. The treatment algorithm includes, when possible, gross-total resection as these tumors are extremely aggressive. When these tumors occur intracranially, they are termed malignant intracerebral nerve sheath tumors. The diagnosis hinges on immunohistochemistry and pathological features and often the diagnosis can be delayed for this reason. In this setting, it is critical to utilize intraoperative navigation, thus necessitating the use of fine-cut magnetic resonance imaging (MRI). This report presents a patient who presented with symptoms of obstructive hydrocephalus secondary to an intracranial mass. The patient underwent a full and extensive metastatic workup that was ultimately negative. To complicate things, the patient was fully pacemaker dependent. In this report, we review the literature surrounding this type of tumor, along with a detailed presentation of the case mentioned including the difficulties of cardiac pacing in the setting of MRI.

      Giant cell tumors (GCTs) are rare, benign, and locally aggressive primary bone neoplasms. Spine is seldom affected, especially above the level of sacrum. In this report, we describe a case with GCT of the cervical vertebrae which causes collapse of the corpus. A 32-year-old female presented with gradual neck pain and abrupt paresthesia of the left hand. Computed tomography scan showed C6 vertebral collapse and magnetic resonance imaging demonstrated vertebral plana of C6 by a low signal intensity lesion on T1- and T2-weighted images. Emergent surgical intervention was taken due to the possibility of spinal injury. The tumor was removed by en-bloc resection and histopathological investigation confirmed GCT. In most of the cases, en-bloc resection of GCTs of the spine is not feasible. Despite the location and close contact of the lesion with spinal cord, later approach was successful for our case; thus, appropriate differential diagnosis for vertebral column lesions as well as selecting an optimum treatment is mandatory.

      Epidermoid tumors are rare benign neoplasms. They commonly occur in the parasellar region and the cerebellopontine angle but may sometimes present in the so-called petroclival region, or beyond the boundaries of this location. For those that are localized in multiple compartments, staged surgeries, extensive transtemporal approaches, or somewhat limited extended middle fossa approach are generally performed. Although a good resection can be achieved by these approaches, they carry relatively high morbidity and mortality. We report a case of epidermoid tumor with infra- and supratentorial extensions, and propose a combined retrosigmoid-paramedian supracerebellar transtentorial approach as an alternative to classical transtemporal approaches.

      Lumbar disc herniation is the most common cause of radiculopathy. In most cases, the chief complaint is associated with radicular pain due to nerve compression on the herniated side. However, a radicular pain contralateral to the herniation side is an unusual finding rarely reported in the literature. Here, a case of right lower limb radicular pain in the presence of left extruded L4–L5 disc herniation is reported. Management of the patient is discussed in addition to a review of the literature regarding hypotheses on the mechanism of this unusual situation.

      Primary intracranial melanoma is an uncommon entity and only case reports have been published in the literature. We report a case of an elderly male who was operated with a preliminary diagnosis of meningioma, but it proved to be a histological surprise as it came out to be melanoma with no primary anywhere in the body.

      Juvenile xanthogranuloma (JXG) is a benign, non-Langerhans cell histiocytic proliferative disorder. We report a case of solitary JXG in an infant presenting as an intraspinal mass. Awareness of this mode of presentation is very important as subsequent prognosis differs from other tumors at the same location. JXG is a self-limiting dermatologic disorder usually occurring in first two decades of life. On rare occasion, it has been reported at extra-cutaneous sites such as central nervous system (CNS), eyes, liver, spleen, lungs and kidneys, and in other age groups. Isolated CNS involvement is extremely rare, especially in the spinal cord.

  • Widespread intra-abdominal carcinomatosis from a rhabdoid meningioma after
           placement of a ventriculoperitoneal shunt: A case report and review of the
           literature

      Intra-abdominal metastasis (IAM) of central nervous system (CNS) tumors via ventriculoperitoneal shunt (VPS) is rare but has been previously reported (e.g., germinomas and medulloblastomas). However, there has been no previous report in the literature involving meningiomas. A case of primary rhabdoid meningioma with widespread intra-abdominal carcinomatosis after placement of a VPS in a 36-year-old man is described. The patient underwent preoperative angioembolization of the tumor, craniotomy, and surgical excision, followed by postoperative gamma knife radiosurgery. Five months later, he underwent a decompressive craniectomy and surgical excision for tumor recurrence causing raised intracranial pressure and communicating hydrocephalus, necessitating placement of a VPS. One month after placement of the VPS, the patient developed abdominal distension and confusion. He was treated for a VPS infection, and the shunt was explanted. He continued to deteriorate with high output from the peritoneal drain placed at the time of shunt explantation. An exploratory laparotomy revealed multiple diffuse peritoneal and omental nodules which had the same histopathological and immunohistochemical morphology as the primary tumor. We reviewed the current literature on IAM of primary CNS tumors via VPS, which revealed that patients belonging in the pediatric age group, of the male gender, and with a primary intracranial germinoma or medulloblastoma have a higher incidence of IAM. Majority of IAM occurred within 2 years of VPS placement, and patients most commonly present with abdominal distension and ascites. Treatment after diagnosis is varied and the prognosis is poor, with more than half of the patients dying within a year. It is vital for clinicians to maintain a high index of suspicion for similar patients, as early intervention could potentially improve patient outcomes and patient expectations managed more effectively.

      Arachnoid cysts (ACs) within the fourth ventricle are rare, and only a few cases have been reported in the literature. These are benign lesions within the arachnoid membrane, and they have been reported to occur in almost all locations where arachnoid is present. Different procedures have been performed to restore a normal cerebrospinal fluid dynamic and/or pressure, including shunting and partial or complete excision of the cyst by open microsurgery or endoscopic fenestration. We report the case of a fourth ventricle AC successfully treated using only endoscopic anterior trans-frontal cyst fenestration/marsupialization and standard third ventriculostomy. Clinical and technical features are discussed, along with the pertinent literature.

      Nondysraphic intramedullary spinal cord lipomas are even rarer. We present a thoracic intramedullary lipoma which spontaneously decreased in size following surgical debulking. A 3-year-old girl was admitted to our department with complaints of back pain since 1 year and progressive difficulty in walking since 6 months. Her magnetic resonance imaging (MRI) revealed T8-9 intramedullary mass showing increased signal intensity in both T1- and T2-weighted images. The patient was operated with a T8-9 laminoplasty and debulking, and internal decompression of the tumor was made. Histologically, the tumor was uniformly composed of mature adipose tissue revealing a lipoma. First-month control MRI revealed the rest mass almost the half volume of the preoperative mass. The 2nd year MRI revealed the size of the lipoma was spontaneously decreased to almost half of postoperative size and 3rd year was the same as the 2nd year with a mild kyphosis. Decompression and debulking with or without duraplasty is the most appropriate treatment for symptomatic patients. Dietary measures with control of fat intake and long-term follow-up are also suggested.

      Choroid plexus papilloma is a rare intracranial neoplasm. These lesions most commonly present in the fourth ventricle in adults and lateral ventricle in children. Herein, we report a case of a 57-year-old male with complaint of backache of few weeks duration. Magnetic resonance imaging revealed an intradural and extramedullary space occupying lesion at D8 level. Histology showed multiple free-floating papillae with a central fibrovascular core. The cells showed immunoreactivity for vimentin, glial fibrillary acidic protein, synaptophysin, S-100 protein, and cytokeratins (CK, CK7).
