A large false aneurysm of the right ventricle within a giant epicardial lipoma

Lipomas, which account for approximately 10% of all neoplasms of the heart, may be detected in asymptomatic patients by chance during echocardiography . CT scan, or MRI scan. Occasionally, lipomas are complicated by al arrhyth mias. We describe a patient who presented with severe cardiomegaly and paro xysmal supraventricular tachycardia. An MRI scan showed a large intraperica rdial lipoma with two large cavities inside communicating with each other a nd with the light ventricular chamber through a defect of the right ventric ular wall. The mass was partially removed, and the right ventricle was patc hed. Surgery combined with antiarrhythmic therapy resulted in a good short- term result.
