Arteriovenous malformation of the spinal cord and cauda equina fed by branches of the internal iliac artery and associated with vertebral hemangiomas.

A rare case of an arteriovenous malformation (AVM) of the spinal cord is presented. The patient was a 35-year-old man who experienced progressive paraparesis and rectovesical disturbances. In this patient a spinal AVM was fed by branches of the left internal iliac artery and was associated with a sacral hemangioma. An additional hemangioma of the third lumbar vertebral body was also found. On reviewing the literature, only 4 cases, including ours, of spinal AVM with feeding vessels originating from the internal iliac artery were found. One of these patients had an associated vertebral hemangioma.
