Dural arteriovenous fistula of the cavernous sinus with brainstem edema

Dural arteriovenous fistula of the cavernous sinus is usually a benign disease and rarely has brainstem edema as its complication. We present a patient with dural arteriovenous fistula of the cavernous sinus and brainstem edema. The brainstem edema resolved after embolization. Embolization should be considered first whenever brainstem edema occurs, progressive visual deterioration or increased intracranial pressure is encountered in a case of dural arteriovenous fistula of the cavernous sinus.
