Dural arteriovenous fistula involving the anterior condylar canal

Abstract

Dural arteriovenous fistula (DAVF) of the anterior condylar canal is a rare subgroup of posterior fossa DAVF. Successful treatment of this DAVF requires an accurate image diagnosis and the knowledge of the anatomy of the anterior condylar confluent. We present the imaging features of angiography and MR angiography of a 54-year-old man, who presented progressive right synchronous tinnitus due to a DAVF of the anterior condylar confluent, successfully treated by transvenous embolization.

Keywords: Dural arteriovenous fistula; anterior condylar confluence; anterior condylar vein; embolization; hypoglossal canal.
