An arteriovenous malformation is an anomaly of capillary development that results in a direct connection between branches of an artery and veins, with no intervening capillary network. Vascular malformations of the mediastinum presenting as mediastinal masses are very rare. We report a histologically proven case of a posterior mediastinal arteriovenous malformation in a 42-year-old man that was incidentally detected by chest radiography during a routine health check. We discuss arteriovenous malformation and review the literature findings.

Key Words: Arteriovenous malformations; Vascular tumors; Mediastinum; Computerized tomography
