Long-standing tentorial dural arteriovenous fistula presenting as progressively worsening cervical myelopathy by degenerative cervical intervertebral disc: a case report
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.
