Perfusion tomography in early follow-up of acute traumatic subdural hematoma: a case series.

Perfusion Computed Tomography (PCT) is an alternative tool to assess cerebral hemodynamics during trauma. As acute traumatic subdural hematomas (ASH) is a severe primary injury associated with poor outcomes, the aim of this study was to evaluate the cerebral hemodynamics in this context. Five adult patients with moderate and severe traumatic brain injury (TBI) and ASH were included.

Endoscopic resection of sellar and suprasellar epidermoid cyst: report of two cases and review of literature.

Introduction: Epidermoid cysts (EC) are lesions developing from neuroectodermal epithelial cells. They represent 1-2% of all intracranial tumors and are usually found in cerebellopontine angle and parasellar regions. To the best of our knowledge, only 27 cases have been reported of EC in sellar and suprasellar region.

Sporadic hemangioblastoma of cauda equina: An atypical case report.

Background: Hemangioblastomas account for about 1%-3% of all central nervous system tumors. They are usually associated with the Von Hippel-Lindau syndrome and typically occur in the posterior fossa, or throughout the spinal neuraxis. Here, we report the unusual case of a sporadic cauda equina hemangioblastoma.

Diffuse spinal spreading following previous intracranial intradural chordoma resection: A rare case report.

Introduction: Chordoma is a malignant tumor that usually involves the axial skeleton. Intradural chordomas are even rarer and 37 cases have been reported to the best of our knowledge. We present a case of a patient with an atypical metastatic diffuse intradural spinal involvement.

Role of Transnasal Endoscopic Surgery in the Treatment of Superficial Siderosis of Central Nervous System Secondary to Clivus Arachnoidocele: Report of Successful Case and Literature Review.

Background: Superficial siderosis (SS) of the central nervous system is a disease characterized by deposition of hemosiderin in the leptomeninges (arachnoid and pia mater) due to chronic intradural bleeding. One of the etiologic mechanisms proposed is a dural breach secondary to trauma with a consequent arachnoidocele in contact with an exuberant venous plexus. We describe a unique case of clival arachnoidocele treated by an endoscopic endonasal approach and closure of the defect with fat and nasoseptal flap.
