A rare case of posterior fossa dural arteriovenous fistula with cerebellar circulation disorder is reported. A 64-year-old male was admitted to a hospital with complaints of nausea, vertigo and mild headache. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed cerebellar infarction. Then, he was sent to our hospital. He had complaints of cerebellar signs and nystagmus. Cerebral angiography showed dural AVF of the posterior fossa and occlusion of the left transverse-sigmoid sinuses. Because his condition deteriorated, embolization of the left middle meningeal artery, ascending pharyngeal artery and occipital artery was performed selectively on August 18. Subsequently, isolation of dural AVF was performed on August 19. After the operation he improved and was able to walk with a stick. Controlled angiography revealed the disappearance of dural AVF. This case suggested that AV shunt is essential for the progression of venous infarction.
报告了一例罕见的伴有小脑循环障碍的后颅窝硬脑膜动静脉瘘。一名64岁男性因恶心、眩晕和轻度头痛入院。计算机断层扫描（CT）和磁共振成像（MRI）显示小脑梗死。随后，他被送往我院。他有小脑体征和眼球震颤的症状。脑血管造影显示后颅窝硬脑膜动静脉瘘以及左侧横窦-乙状窦闭塞。由于他的病情恶化，于8月18日选择性地对左脑膜中动脉、咽升动脉和枕动脉进行了栓塞。随后，于8月19日进行了硬脑膜动静脉瘘隔离术。术后他病情好转，能够拄着拐杖行走。控制性血管造影显示硬脑膜动静脉瘘消失。该病例提示动静脉分流对于静脉梗死的进展至关重要。
