摘　　要：颅内硬脑膜动静脉瘘占颅内动静脉畸形的10%～15%,可引起颅内出血或其他神经功能缺损,但其临床表现缺乏特异性,CT 和 MRI 改变不典型,易被忽视而漏诊或延误诊断。临床医生对该病的认识和高分辨率影像学检查对快速准确诊断很关键,及时治疗可防止死亡或残疾。文章对相关文献进行了综述,以提高对硬脑膜动静脉瘘的认识,尽早明确诊断并予以恰当的治疗。Intracranial dural arteriovenous fistula accounts for 10% to 15% of intracranial arteriovenous malformations. It may cause intracranial hemorrhage or other neurological deficits, but its clinical manifestations are lack of specific, the changes of CT and MRI are not typical, and it is easily to be ignored and missed or delayed. Clinicians＆#39; awareness of the disease and the high resolution imaging examinations are critical for rapid and accurate diagnosis. Timely treatment may prevent death or disability. This article reviews the relevant literature in order to improve the understanding of intracranial dural arteriovenous fistula, to be diagnosed early and treated appropriately.
