Dural arteriovenous fistulas (dAVf) are uncommon, acquired vascular lesions. Their location and vascular anatomy produces varied signs and symptoms and are misdiagnosed as other vascular anomalies. We present an atypical case of a dAVf identified along the left optic nerve sheath. The patient presented with progressive ophthalmological signs and was initially misdiagnosed with a left carotid-cavernous fistula. The aetiology, classification and treatment options are discussed.
硬脑膜动静脉瘘(dAVf)是一种罕见的后天性血管病变。其位置和血管解剖结构会产生各种体征和症状,常被误诊为其他血管异常。我们报告一例沿左侧视神经鞘发现的非典型硬脑膜动静脉瘘病例。该患者出现进行性眼科体征,最初被误诊为左侧颈动脉海绵窦瘘。本文将讨论其病因、分类及治疗选择。
