We report a case of totally anomalous pulmonary venous connection in which the two pulmonary veins from the left lung joined to form a common vein which then passed across the midline into a hypoplastic right lung and, after receiving small veins from the right lung, passed inferiorly, exiting the lung below the hilum as a “scimitar” vein and terminating in the inferior caval vein. A separate pulmonary vein from the right lung passed inferiorly independently and joined the “scimitar” vein before it entered the inferior caval vein. There was an associated hypoplastic left heart syndrome.

Mycotic aneurysms of the pulmonary trunk are a rare but recognized complication of infective endocarditis. They are usually associated with infected congenital heart lesions, and especially with persistent patency of the arterial duct. This report deals with a patient with a persistent duct and aortic coarctation who developed a mycotic aneurysm of the pulmonary trunk secondary to infective endocarditis. The lesion was evaluated before and after surgery by magnetic resonance imaging.
