[Intratympanic meningioma. Apropos of a case]. / Méningiome intra-trympanique. A propos d'un cas.

A 40 year old woman presented with a meningioma of the intratympanic region, a very rare localization which raises problems of differential diagnosis from jugular glomus tumors. A brief historical survey and complete etiopathogenic study are presented, and clinical features and results of complementary examinations, particularly angiography and computed tomography, are described. Treatment is exclusively surgical and diagnosis is confirmed with certitude by histopathology only.
