Abstract：
BACKGROUND: Spinal dural arteriovenous fistula is the most common spinal vascular malformation. It usually presents with neurological deficits due to venous congestive myelopathy. Sometimes, however, the symptoms are radicular and can imitate those of a disc hernia or synovial cyst.
METHODS: In this illustrated case, a 34-year-old male patient presented with radicular pain due to nerve root compression. In the magnetic resonance imaging (MRI) examination of the spine, a synovial cyst was suspected, so the patient underwent no further examination before surgery. Intraoperatively, the authors were surprised to see a vascular malformation, which was shown to be an extradural arteriovenous fistula according to the histopathological examination.
CONCLUSIONS: In atypical MRI findings of the spine, vascular malformations should be considered. In cases with a spinal dural arteriovenous fistula, the thrombosis risk can be high and lead to a need for prolonged anticoagulation.

摘要：
背景：硬脊膜动静脉瘘是最常见的脊髓血管畸形。由于静脉充血性脊髓病，通常表现为神经功能缺损。有时候,然而,症状是神经根，可以模仿椎间盘疝或滑膜囊肿。
方法：在此示例中，一名34岁的男性患者因神经根受压而出现神经根疼痛。在脊柱的磁共振成像（MRI）检查中，怀疑有滑膜囊肿,所以病人在手术前没有接受进一步的检查。术中,作者惊讶地看到血管畸形，根据组织病理学检查显示为硬膜外动静脉瘘。
结论：在脊柱的非典型MRI发现中，应考虑血管畸形。在硬脑膜动静脉瘘的病例中，血栓形成的风险可能很高，并导致需要长期抗凝治疗。
