title: Facial nerve schwannoma in the cerebellopontine cistern. Findings on high resolution CT and MR cisternography.
abstract: We report a case of facial nerve schwannoma originating in the cerebellopontine cistern, diagnosed by cochlear sensorineural hearing loss, and involvement in the facial nerve canal and the anterior epitympanic recess. Precise analyses of neuro-otological and neuroradiological studies are crucial to obtain an accurate preoperative diagnosis.
