Cavernous dural arteriovenous fistula (DAVF), which usually presents with conjunctival injection, proptosis, loss of visual acuity, and ophthalmoplegia, is a rare cause of ophthalmoplegia. Thus, it may be overlooked when the typical symptoms are lacking. There have been some cavernous DAVF case reports presenting with isolated oculomotor, abducens and trochlear nerve palsy. We report a patient presenting with isolated oculomotor palsy, caused by cavernous DAVF, which was treated by transvenous coil embolization. This case suggests that cavernous DAVF should be considered in the differential diagnosis of isolated oculomotor nerve palsy and for which case - selective angiography and embolization may be helpful in reaching a diagnosis and providing a guide for optimal treatment.
