[Angiomatous malformation of the inner auditory canal with the leading symptoms of vertigo and tinnitus].
A case of a rare arteriovenous malformation in the internal auditory canal is reported. It caused unilateral tinnitus, facial weakness, trigeminal hypesthesia, and vertigo with lateropulsion. The audiological and otoneurological findings together with air-cisternography a CT scan had indicated an intrameatal tumor. An extended trans-temporal exposure of the internal auditory canal demonstrated an angiomatous lesion compressing the adjacent seventh and eighth cranial nerves. It could be removed safely by a second-stage lateral suboccipital approach to the cerebello-pontine angle.
