Giant cardiac lipoma: report of a case.

Cardiac lipomas are extremely rare benign tumors. We report a case of a 41-year-old man who was admitted because of cardiomegaly and a feeling of discomfort in his chest. Computed tomography and magnetic resonance imaging studies showed a large mass occupying the mediastinum and pericardial space. The patient underwent resection of a lipoma which weighed 1100 g and had a pedicle 6 cm in diameter, connected to the epicardial surface of right ventricle infundibulum.
