Successful Endovascular Treatment of Trigeminal Neuralgia Caused by a CarotidCavernous Fistula: Case Report

Abstract

<jats:p>Dural arteriovenous fistulas (DAVFs) of the cavernous sinus are arteriovenous connections located in the dura mater leaflets of this region. The usual presentation of a DAVF is predominantly ocular, with symptoms such as diplopia, conjunctival injection, involvement of cranial nerves III/IV/VI, exophthalmos, and chemosis. Trigeminal neuralgia caused by a cavernous DAVF is extremely rare. To the best our knowledge, this is only the fourth report in the world literature. We describe the case of a patient treated by embolization in whom the only presenting symptom of DAVF was trigeminal neuralgia. After endovascular treatment, the patient became asymptomatic.</jats:p>
