title: Angiography-induced closure of perimedullary spinal arteriovenous fistula.
abstract: Type 4 spinal vascular malformations are called perimedullary arteriovenous fistulae, in which there is a shunt between a radicular artery and intradural veins. We report the spinal MR imaging and angiography findings of the angiography-induced closure of a type 4 spinal vascular malformation.
