Background: Dural arteriovenous fistula (dAVF) is an abnormal arteriovenous shunt in the dura mater and is a relatively rare disease. We experienced a case of symptomatic dAVF that developed at contralateral cavernous sinus after operation of the sphenoid ridge meningioma. Herein, we report our case along with the relevant literature. Case report: A 69-year-old woman underwent a surgical removal of left sphenoid ridge meningioma, which gradually increased. The operation was conducted via left frontotemporal craniotomy. Although there were no perioperative complications, she became aware of right pulsatile tinnitus six months later, and double vision developed one year after the operation. A close examination was conducted, and digital subtraction angiography revealed the dural shunt at right cavernous sinus in the arterial phase. We diagnosed cavernous sinus dAVF, and performed coiling intravenously, resulting in complete occlusion of the shunt. The symptoms of the patient disappeared soon after the operation, she has had an uneventful course after discharge without recurrence of symptoms, as well as tumors and dAVF. Conclusion: We experienced a case in which dAVF developed after the excision of meningioma, and considered multiple mechanisms of development of dAVF in this case such as changes in blood flow of dural arteries and veins, and intracranial hemodynamics.
