We report a rare case of long-standing asymptomatic tentorial dural arteriovenous fistula (DAVF) presenting as symptomatic progressive cervical myelopathy which was caused by the protrusion of degenerative cervical intervertebral discs into the spinal canal and compression of the anterior spinal vein. The cervical spinal canal was narrowed, and the spinal cord was compressed anteriorly by protrusion of cervical intervertebral discs at the C6-7 level. The intervertebral discs compressed the draining vein of the tentorial DAVF (the anterior spinal vein) so venous congestion of the spinal cord resulted in cervical myelopathy only above the C6 level.
我们报告一例罕见的长期无症状天幕硬脑膜动静脉瘘（DAVF）病例，表现为症状性进行性颈髓病，其由退行性颈椎间盘突入椎管并压迫前脊髓静脉引起。颈椎管狭窄，C6-7 水平颈椎间盘突出使脊髓前受压，椎间盘压迫天幕 DAVF 的引流静脉（前脊髓静脉），导致仅 C6 以上脊髓静脉淤血，出现颈髓病。
