Intracranial dural arteriovenous fistulas (DAVFs) are abnormal arteriovenous connections that lie within the dura. Intraosseous DAVFs involving diploic venous system are extremely rare. A 46-year-old woman presented with headache and right pulsatile tinnitus for three weeks. The tinnitus started after yelling. Digital subtraction angiography revealed DAVF within the basal portion of right parietal bone along the middle meningeal artery (MMA) groove. The fistula was fed by frontal branch of right MMA and drained into right transverse sigmoid sinus junction through dilated middle meningeal vein. The intraosseous DAVF involving diploic vein was successfully obliterated with Onyx embolization via transarterial route.
颅内硬脑膜动静脉瘘(DAVF)是位于硬脑膜内的异常动静脉连接。累及板障静脉系统的骨内DAVF极为罕见。一名46岁女性因头痛和右侧搏动性耳鸣3周就诊。耳鸣在大喊后开始。数字减影血管造影显示右顶骨基底部沿脑膜中动脉(MMA)沟存在DAVF。瘘由右MMA的额支供血,通过扩张的脑膜中静脉引流至右横窦乙状窦交界处。通过经动脉途径用Onyx栓塞成功闭塞了累及板障静脉的骨内DAVF。
