Colloid cyst in the third ventricle is a common entity, whereas a variant of it, namely xanthogranulomatous, is quite rare. The closest imaging differential diagnosis is a purely third ventricular craniopharyngioma. We herein describe a case of xanthogranulomatous colloid cyst presenting with hydrocephalus.
Pilocytic atrocytoma(PA) is a World health organization (WHO) grade I astrocytoma. It most commonly develops during first two decades of life with predilection for infratentorial region. The tumor shows a favorable behavior and patients usually have excellent long term improvement. Histologic progression and features of anaplasia is a rare event in… (More)
A 52-year-old female presented with slowly progressive left lower limb polyradiculopathy. MRI of the lumbar region revealed an extradural dumbbell mass at L3 vertebral level, isointense on T1W and hyperintense on T2W images with homogenous contrast enhancement and extending into paraspinal region through left L3/4 foramen. L2 to L 4 left hemilaminectomy and… (More)
We present a male child with primary Ewing's sarcoma arising from ethmoid sinuses with intradural and extracranial extension (bilateral nasal cavities, orbits, and maxillary sinuses). This is a rare condition. He presented with recurrent episodes of epistaxis for 2 years, sudden onset rapidly progressive bilateral proptosis, with painful restriction of… (More)
PURPOSE Tentorial meningiomas, comprising approximately 3-6% of all intracranial meningiomas, are complex entities with an intricate relationship to surrounding structures and require multiple surgical approaches. In the present study, the rationale for deciding the approaches for TMs and the perioperative management dilemmas were evaluated. METHODS… (More)
BACKGROUND Surgical management of giant medial sphenoid meningiomas (> or =5 cm in maximum dimension) is extremely challenging due to their intimate relationship with vital neural structures like the optic nerve, cranial nerves of the cavernous sinus and the cavernous internal carotid artery. Their surgical management is presented incorporating a… (More)
