Cerebellopontine Angle Epidermoid Cyst: Case Report
Abstract: Epidermoid cysts are rare congenital tumors of the central nervous system (CNS), histologically benign and slow- growing 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 the case of a patient with a paucisymptomatic epidermoid cyst of the CPA.
