Intracranial and intratemporal meningiomas with primary otologic symptoms.

Intratemporal extensions of cerebellopontine angle (CPA) meningiomas are unusual and primary intratympanic meningiomas are extremely rare. The initial symptoms of both types are otologic. The presenting symptoms of even large meningiomas of the cerebellopontine angle can also be otologic. In this article we report the clinical features, diagnosis, and management of five CPA meningiomas, three combined intratemporal and CPA meningiomas, and one primary intratympanic meningioma.
