A VERY RARE CASE; CARDIAC LIPOMA

Cardiac lipomas are rare primary benign tumors of the heart. They make up only 8.4% of primary heart tumors. (1) The etiology of these tumors is not certain, but some publications have hypothesized that cardiac lipomas are affected by HMGA2-LPP gene fusion. (2) Cardiac lipomas are mostly asymptomatic and are detected incidentally in routine cardiac screening tests. When cases are symptomatic, symptoms vary depending on the location and size of the mass. For example, signs of stenosis and arrhythmias occur when the tumor is in the superior vena cava. The most common locations are the right atrium and left ventricle. In addition to these locations, they can be seen in any intracardiac and epicardial locations. Echocardiography and cardiac MRI can be used as diagnostic methods. We report a very rare case of cardiac lipoma, which narrows the right atrial inflow and extends to the superior vena cava.
