We present an unusual case of a spinal dural arteriovenous malformation (AVM) which produced compression radiculopathy of the left S1 nerve root. The nerve root was compressed by epidural vessels, draining vessels, and the nidus, without the characteristic myelographic findings of a dural AVM. No feeding vessels could be identified. It is important to consider the possibility of a spinal dural AVM in middle-aged patients who suffer lumbosacral radiculopathy, even if myelography does not demonstrate the characteristic findings.
我们报告一例罕见的脊髓硬脊膜动静脉畸形（AVM），该畸形导致左侧S1神经根压迫性神经根病。神经根被硬膜外血管、引流血管和病灶压迫，没有硬脊膜AVM典型的脊髓造影表现。未发现供血血管。对于患有腰骶神经根病的中年患者，即使脊髓造影未显示典型表现，也应考虑脊髓硬脊膜AVM的可能性。
