%X Metameric spinal cord arteriovenous malformations (AVMs) are rare lesions characterized by an intradural and extradural component. They are difficult to treat surgically by the endovascular route. We report a case in which symptomatic relief was achieved by embolization of the extradural component only. A 35-year-old woman presented with acute worsening of back pain, weakness in the left leg and urinary retention. Spinal angiography showed a metameric spinal cord AVM with partial common venous drainage of the extradural and intradural components. Targeted embolization of the extradural component led to dramatic improvement of the patient¡¯s symptoms, probably by achieving venous decongestion. She remains neurologically stable at two years¡¯ follow-up
