Metameric spinal AVM: Long-term symptomatic relief achieved by embolization of the extradural component

摘要

Background: 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.
