Transvenous embolization of an intraosseous dural arteriovenous fistula of the anterior condylar vein with anomalous venous drainage causing ocular manifestations.

We report a patient with a rare dural arteriovenous fistula of the anterior condylar vein, who presented with unusual clinical symptoms due to the anomalous venous drainage. The patient had progressive ocular signs, a dilated venous pouch at the skull base and, on angiography, retrograde venous drainage into the superior ophthalmic vein. Transvenous embolization of the venous pouch produced complete amelioration of the ocular symptoms. Such treatment may be curative for dural arteriovenous fistulas of the anterior condylar vein.
