Epidermoid cysts are rare congenital tumors of the central nervous system (CNS), histologically benign and slowgrowing lesions. Their frequency among primitive intracranial tumors is about 1% and they account for 40% of all intracranial epidermoid of the cerebellopontine angle (CPA); there they constitute the third most frequent neoplasm (5%), after acoustic neuromas and meningiomas. We report ...

Sixty-nine patients who had neurosurgical treatment for acoustic neuroma by one of two different techniques were studied with a view to determining the incidence of postoperative epilepsy. Fourty-five patients who had larger tumours underwent a combined translabyrinthine and transtentorial neurosurgical approach. For the others with smaller neuromas a translabyrinthine method was used. Only the...

account for account for 8% of all primary brain tumours in adults, with most cases being acoustic neuromas, intraparenchymal schwannomas of the brain are rare. Gibson et al. (1) reported the first English-language account of an intraparenchymal intracerebral schwannoma in 1966. Since then, several other cases of this neoplasm have been reported (2, 3). We present a case of an unusual intracrani...

Acoustic neuromas are the most common tumor in the cerebellopontine angle (CPA) but are rare in the general population. Paragangliomas are rarer still and, in a minority of cases (20%), are known to be caused by errors in the SDHD gene. Mutations in this gene are highly penetrant when inherited paternally but not maternally. We present the first reported case of a patient with a CPA tumor and a...

Acoutic neuromas operated at UMMC from 2001 to 2006 were retrospectively reviewed. There were a total of 27 cases. All tumors were large, measuring more than 2 cm. Hearing loss was the most common presenting symptom (63%), followed by headache (52%), dysequilibrium (30%), facial numbness (30%), tinnitus (26%) and gait disturbances (15%). Eleven (41%) of patients had hydrocephalus at the time of...
