Abstract:
Oculomotor nerve palsy due to a venous varix arising from flow anomalies caused by a dural arteriovenous fistula (AVF) is a rare phenomenon. We report a case of surgical third nerve palsy with a rare underlying AVF as the cause and discuss in detail the patho-anatomy and its significance. A tentorial dural AVF mimicking the arterial circle was found with multiple varix formation causing compressive oculomotor palsy. This was treated successfully with Onyx™ injection with a satisfactory angiographic result and complete resolution of symptoms.
