Cardiac lipomas are very rare benign tumors of the heart. They are usually asymptomatic and are often an incidental finding on cardiac imaging. This case report involves an 82-year-old female with a history of diabetes admitted because of poor glycemic control. An echocardiogram requested because of arrhythmias and heart failure revealed a tumor in the right atrium. Computed tomographic and ultrasound appearances were consistent with a lipoma and demonstrated a large mass in the right atrium, causing a significant stenosis of the superior vena cava but no clinical symptoms or signs of superior vena cava syndrome.
