摘　　要：Dural arteriovenous fistulas(DAVFs)are rare vascular abnormalities that comprise 10%-15%of all intracranial arteriovenous malformations.The pathogenesis of DAVFs is still uncertain,although growing angiographic evidence supports the acquired characteristics of this vascular disease.Here,we present the case of a 39-year-old man with incidental bilateral paraophthalmic aneurysms who experienced spontaneous retroocular pressure and mild headache.Magnetic resonance angiography revealed enlargement and a change in the shape of the right paraophthalmic aneurysm.The patient underwent a right pterional craniotomy for the intracranial aneurysms.Five months later,he presented with progressive pulsatile tinnitus.A diagnostic angiogram demonstrated a Cognard type I DAVF of the right sigmoid sinus.Based on this case,angiography monitoring is recommended.Herein we review and summarize postoperative DAVF cases.Common causes of acquired DAVFs and treatment selection are discussed based on relevant literature.
