Concomitant occurrence of vestibular schwannoma and epidermoid tumor

Abstract

The occurrence of two tumors adjacent to each other at the same site is very rare. We present here, a patient with a vestibular schwannoma found adjacent to an epidermoid tumor in the cerebellopontine angle.

Key words

Cerebellopontine angle - epidermoid - schwannoma
