Spinal vascular malformations are uncommon yet important spinal pathologies commonly classified in congenital and acquired lesions. Spinal lipomas consist of three subtypes: intramedullary lipomas, lipomyelo(meningo)celes and lipomas of the filum. Although the association of spinal arteriovenous malformations (AVM) with other congenital anomalies is well known, the coexistence of dural arteriovenous fistulas (AVF) and tethered spinal cord is exceptionally rare and only eight cases have been reported. We present two cases from our institution and speculate on the possible origin of such a rare but insidious association. We review the current literature with a focus on possible pitfalls in diagnosis and treatment.
脊髓血管畸形虽不常见，但却是重要的脊髓病变，通常分为先天性和后天性病变。脊髓脂肪瘤有三种亚型：髓内脂肪瘤、脂肪脊髓（脊膜）膨出和终丝脂肪瘤。虽然脊髓动静脉畸形（AVM）与其他先天性异常的关联已为人熟知，但硬脊膜动静脉瘘（AVF）与脊髓栓系并存极为罕见，仅有8例报道。我们报告了本院的两例病例，并推测这种罕见但隐匿关联的可能起源。我们回顾了当前文献，重点关注诊断和治疗中可能存在的陷阱。
