title: CT and DSA appearances of a ruptured congenital arteriovenous malformation of the posterior mediastinal aorta.
abstract: A case of symptomatic congenital arteriovenous malformation detected in an adult patient is presented. The diagnosis was not suspected clinically but was demonstrated by CT and digital subtraction angiography. Although very rare, a congenital arteriovenous malformation of the posterior mediastinal aorta could present as a catastrophic event if it ruptures. Serpiginous vascular channels in the retro-oesophageal posterior mediastinum on CT and angiography should raise the possibility of an arteriovenous malformation.
