A patient with a spinal intradural arteriovenous malformation (AVM) at the conus medullaris concomitant with a sacral dural arteriovenous fistula (AVF) of the filum terminale is reported. A 44-year-old-male presentied with bilateral leg weakness and urinary incontinence for several months. Spinal angiography demonstrated two lesions: one was spinal intradural AVM at the conus medullaris supplied by the anterior spinal artery; the other was sacral dural AVF of the filum terminale supplied by the middle sacral artery. Although multifocal spinal cord AVMs have been reported, this is the first case report of two different types of vascular malformations coexisting in one patient. The arterial supply of the dural AVF of the filum by the middle sacral artery is also first demonstrated in the literature. The patient was treated successfully by surgical approach for both lesions in the same operation.
报告了1例圆锥部脊髓硬膜内动静脉畸形（AVM）合并终丝骶部硬脊膜动静脉瘘（AVF）的患者。一名44岁男性，出现双侧腿部无力和尿失禁数月。脊髓血管造影显示两个病变：一个是由脊髓前动脉供血的圆锥部脊髓硬膜内AVM；另一个是由骶中动脉供血的终丝骶部硬脊膜AVF。虽然已有多灶性脊髓AVM的报道，但这是首例两种不同类型血管畸形共存于同一患者的病例报告。文献中也首次证实了骶中动脉对终丝硬脊膜AVF的动脉供血。该患者通过手术方法在同一次手术中成功治疗了两个病变。
