We report a patient with a petrosal arterio-venous dural fistula draining into the ponto-mesencephalic and medullary venous systems presenting with edema of the brain stem and complete reversal of magnetic resonance imaging (MRI) abnormalities after combined endovascular and surgical treatments. The venous anatomy of the posterior fossa and the significance of the venous involvement as the cause of clinical symptoms and imaging abnormalities in cerebro-medullary vascular lesions are discussed.
我们报告了一例岩骨动静脉硬脑膜瘘,其引流至脑桥-中脑和延髓静脉系统,患者出现脑干水肿,在接受血管内和手术联合治疗后,磁共振成像(MRI)异常完全逆转。本文讨论了后颅窝的静脉解剖结构以及静脉受累作为脑髓血管病变临床症状和影像异常原因的意义。
