Spinal intradural arteriovenous fistula: a case with an unusual presentation

Spinal intradural arteriovenous fistula is a rare type of spinal vascular malformation. It is usually fed by the anterior spinal artery and causes episodic myelopathy in young adults. We present a pediatric patient with such a vascular malformation which was fed directly by a medullary artery. The clinical course, complete radiological study and the excellent outcome will be described in detail. This rare subtype of spinal vascular malformation will be discussed.
