Coexistence of a spinal dural arteriovenous fistula within a dysraphic spinal lesion is a very rare situation. We report a 40-year-old man who presented with low back pain and progressive paraparesis. MR images showed an intradural high signal intensity mass at the L2-L3 level containing irregular signal void structures. Spinal angiography revealed extradural arteriovenous fistula with three connections, drained by a tortuous perimedullary vein.
脊髓硬膜动静脉瘘与脊柱发育异常性病变并存的情况极为罕见。我们报告了一名40岁男性，他因腰痛和进行性双下肢轻瘫就诊。磁共振成像显示L2-L3水平硬膜内有一高信号肿块，内含不规则信号空洞结构。脊髓血管造影显示硬膜外动静脉瘘，有三处分流，由一条迂曲的脊髓周静脉引流。
