title: Pulmonary venous aneurysm presenting as a middle mediastinal mass.
abstract: A large mediastinal mass in a 43-year-old man was proven at thoracotomy to comprise a right superior pulmonary vein aneurysm. Intraoperative transesophageal echocardiography was useful in defining the abnormality. Pulmonary venous aneurysm appears to represent an extremely rare but surgically correctable addition to the differential diagnosis of middle mediastinal masses.
