[Ménière's-like symptoms following meningioma].

A 36-year-old woman who presented with a right sided hearing loss, tinnitus and attacks of dizziness was initially diagnosed with Ménière's disease. A meningioma was found along the posterior surface of the petrosal bone, centred partly on the external aperture of the vestibular aqueduct with no relation to the meatal canal. Removal of the meningial tumour improved the hearing but Ménière's-like symptoms recurred after 18 months despite surgery. Ménière's-like symptoms could hypothetically be caused by changes of the endolymphatic duct or the vein of the vestibular aqueduct.
