Multiple dural arteriovenous fistulae involving the cavernous and sphenoparietal sinuses.

A 72-year-old woman who presented with a unilateral oculomotor nerve palsy was shown to have a very rare condition: multiple dural arteriovenous fistulae (DAVF) involving the cavernous and sphenoparietal sinuses. The sphenoparietal DAVF was cured completely by transarterial embolisation. Symptomatic relief was accomplished by this procedure. The cavernous sinus DAVF progressed to acquire cortical venous drainage, and was obliterated completely by transvenous embolisation.
