Spinal perimedullary arteriovenous fistula, a subtype of spinal arteriovenous malformation, is generally considered to be a congenital lesion by maldevelopment of the spinal vascular system. However, several cases of perimedullary arteriovenous fistula had been reported in the literature, which were thought to be acquired lesions. We presented a case of perimedullary arteriovenous fistula, which was believed to be derived from spinal cord trauma. The etiology and pathophysiology of this case were discussed, and it might provide further insight into the pathogenesis of such lesions.
