Abstract

Objectives: We report a case of an arteriovenous malformation within the internal auditory meatus and cerebellopontine angle, and we discuss its imaging appearances and management. Case report: A 50-year-old man presented with a two-year history of vertigo. Magnetic resonance imaging and magnetic resonance angiography demonstrated a lesion consisting of multiple 'high flow' vessels within the left internal auditory meatus and cerebellopontine angle. Transarterial embolisation was performed, with obliteration of the arteriovenous malformation. Conclusion: Arteriovenous malformations of the internal auditory meatus and cerebellopontine angle are exceedingly rare. It is important that a pre-treatment diagnosis is made, as the management of arteriovenous malformation differs from that of other, more common lesions at this site.
