Primary pediatric cerebellar gliosarcoma

Background: Primary gliosarcomas of the central nervous are rare and very few have been reported in the infratentorial compartment. Here, we describe such a lesion in a 12-year-old male. Case Description: A 12-year-old male presented with headache, ataxia, and vomiting. When Magnetic resonance studies documented a posterior fossa lesion, he underwent placement of a right ventriculoperitoneal shunt followed by a suboccipital craniectomy. The lesion proved to be a primary gliosarcoma. Unfortunately, it recurred 2 years later and required repeated resection. Conclusion: Here, we reviewed the rare case of a 12-year-old male requiring shunt placement and suboccipital craniectomy for a primary gliosarcoma that recurred 2 years later.

✓ A case is reported of hydrocephalus due to overproduction of cerebrospinal fluid (CSF) caused by villous hypertrophy of the choroid plexus in the lateral ventricles. A 7-year-old girl with mental retardation developed gait disturbance; hydrocephalus and a Dandy-Walker cyst were detected on computerized tomography. She was initially treated with a ventriculoperitoneal shunt; however, shunting failed to control the hydrocephalus. The excessive outflow of CSF suggested choroid plexus abnormality, and magnetic resonance (MR) imaging revealed enlargement of the choroid plexus in both lateral ventricles. The patient was therefore diagnosed as having hydrocephalus induced by overproduction of CSF, which was controlled by resection of the choroid plexus. Histological examination showed the structure typical of normal choroid plexus. This is a rare case of villous hypertrophy of the choroid plexus in which MR imaging assisted in the diagnosis.

Post Procedure

Background: Sellar cysts are common in neurosurgery. Around 90% of these are diagnosed as pituitary adenomas. The other 10% are nonadenomatous, inflammatory, infective, metastatic, or cystic in nature. Some rare cysts include dermoid, epidermoid, colloid, and arachnoid. They all have different histological features. The case we present demonstrates a unique cyst with features that are not previously documented. Case Description: A 60-year-old female presented to the neurosurgical department complaining of blurring of vision and severe headache for more than ½ year. Imaging was done which revealed a bony erosive lesion in the region of sella. Magnetic resonance imaging with contrast showed high signals with no contrast enhancement. A clear diagnosis could not be made based on radiology. Surgery was done and sample was sent for histopathology. Based on histopathological report findings, a diagnosis of benign atypical sellar cyst was made. Post procedure, the patient recovered and was discharged. Conclusion: Sellar cysts present similarly. They are differentiated based on their histological features. The sellar cyst we encountered had features different from the ones already described in the literature.

Brown Sequard Syndrome

Background: Symptomatic T1–T2 disc herniations are rare and, in most cases, are located posterolaterally. Posterior approaches may utilize transfacet pedicle-sparing techniques, while the less frequent central/anterolateral discs may warrant anterior surgery. Case Description: Here, we reviewed four cases of symptomatic T1–T2 disc herniations; two patients were paraparetic due to central discs and underwent anterior surgery utilizing a cage construct. The latter two cases had posterolateral discs contributing to a Brown-Sequard syndrome and radiculopathy, respectively; one patient required a transfacet pedicle-sparing procedure, while the second case was managed conservatively. All surgically treated patients recovered fully. Conclusions: We reviewed 4 cervical T1–T2 disc herniations; two central/anterolateral lesions warranting anterior surgical approaches/cages, and 2 lateral discs treated with a posterolateral transfacet, pedicle-sparing procedure and no surgery respectively. Follow-up magnetic resonance studies documented full resolution for the patient with radiculopathy and a posterolateral disc.

Cerebral Cysticercosis

ABSTRACTCerebral cysticercosis is common, but the possibility for repeated occurrence of peritoneal catheter blockage caused by neurocysticercosis (NCC) after two revisions following ventriculoperitoneal shunt placement for hydrocephalus is unusual. Herein, we describe one rare case in which peritoneal catheter revision was performed two times unsuccessfully. Endoscopic cysternostomy rather than peritoneal catheter adjustment was performed successfully, and histopathological examination of excised cystic samples confirmed NCC in our hospital. The present case highlights the need for awareness of NCC as a possible etiology of hydrocephalus, especially in developing countries. Uncommon findings in both lateral ventricles following low-field magnetic resonance imaging scans as well as the rarity of this infection involved in unusual location play important roles in misdiagnosis and incorrect treatment for hydrocephalus; thus, endoscopic cysternostomy, rather than multiple shunt adjustment of the peritoneal end, is recommended in the selected patient. To the best of our knowledge, this is the first report describing the misdiagnosis and inappropriate treatment of hydrocephalus caused by cerebral cysticercosis in China.
