Although hormonal influences, inflammation, trauma, sinus thrombosis, venous hypertension, and congenital origin have been proposed as sources of dural arteriovenous fistulas (DAVFs) in cavernous and sigmoid sinuses, the etiology of these lesions remains controversial. We present a case with a cavernous sinus DAVF developed from viral meningitis which has not been previously described. A 24-year-old male was admitted to our institute because of periorbital pain, decreased vision, pulsatile tinnitus, chemosis, and exophthalmos on the right side after he had suffered viral meningitis four months before. Cerebral angiography demonstrated a cavernous sinus DAVF, which was successfully obliterated with several platinum coils using a transvenous approach. The viral meningitis most likely caused the inflammation, that may be responsible for the occurrence of the cavernous sinus DAVF. Prompt treatment for inflammation may help to prevent the development of DAVFs.
尽管荷尔蒙影响、炎症、创伤、窦血栓形成、静脉高压和先天性因素被认为是海绵窦和乙状窦动静脉瘘（DAVF）的来源，但这些病变的病因仍存在争议。我们报告了一例由病毒性脑膜炎引起的海绵窦 DAVF，以前尚未有报道。一名 24 岁男性因右侧眼眶疼痛、视力下降、搏动性耳鸣、球结膜水肿和眼球突出而被收入我院，他在四个月前患有病毒性脑膜炎。脑血管造影显示海绵窦 DAVF，经静脉途径使用多个铂金线圈成功闭塞。病毒性脑膜炎很可能引起炎症，这可能是导致海绵窦 DAVF 的原因。及时治疗炎症可能有助于预防 DAVF 的发生。
