Medulloblastoma is quite uncommon in the adult population and even rarer in extra-axial site in cerebello-pontine (CP) angle. In this report, a 23-year-old male patient with a two month history of deafness, nausea, vomiting and ataxia is presented. Clinical and radiological findings demonstrated a heterogeneously enhanced extra-axial lesion in the right CP angle. Total excision was performed an...

eight patients with gross lesions of the pons as demonstrated by air contrast study as well as cranial nerve, long tract and cerebellar syrnphomatology, were treated with 240 kilovolt x-ray therapy, .receiving 2,750 to 5,000 r. initial dose with palliamon for most of them, another 2,750 to 5,000 r. intial does palliation for most of them. another child received only 600 r. and was not helped. ,...

The anterior inferior cerebellar artery arises constantly from the basilar artery on each side at the junction of its lowest and middle thirds and passes laterally and downwards to cross the cerebello-pontine angle and the eighth cranial nerve. At this point the internal auditory artery is usually given off, passing almost immediately into the internal auditory meatus. Either immediately before...

Cavernoma is the most common vascular malformation of the brain with an incidence of 0.4-0.5%, prevalence of 0.6 per 100,000 inhabitants, predominance in males between 20-40 years old, and predominance of 25% in children [1-4]. Brainstem cavernomas are rare (18%) and present a bleeding rate higher than supratentorial cavernomas; they are more common in the pons (61%), with an estimated bleeding...

Multi-segment Facial Nerve Schwannoma (MFNS) is a very rare tumor, benign in nature and can arise anywhere along the course of facial nerve from its origin cerebello-pontine angle to extra cranial ramification parotid space head neck. It mimic like vestibular schwannoma other schwannoma. The most common clinical presentation palsy depending upon segment involved. We report case multi-segment ex...
