Acquired Spinal Arteriovenous Fistula Presenting as Brown-Séquard Syndrome and Endovascular Treatment Outcome.

BACKGROUND: Brown-Séquard syndrome is typically caused by penetrating trauma to the cervical spinal cord; however, other compressive and vascular occlusive etiologies have been previously described. It is extremely uncommon to have a delayed presentation as an extramedullary compressive lesion from the venous varix of an acquired spinal arteriovenous fistula. CASE DESCRIPTION: We present a case of a patient in the fifth decade of life, with a remote history of gunshot wound to the left thorax with progressive left-sided weakness and contralateral pain and temperature sensory loss secondary to cord compression from an acquired spinal arteriovenous fistula. CONCLUSIONS: Subsequent treatment occurred with coil embolization with good outcome.
