title: Left ventricular lipoma with pseudoaneurysm-like appearance.
abstract: We describe an extremely rare cardiac lipoma, with electrocardiographic changes in ST segments and T waves, suggesting ischemic heart disease. The abnormal electrocardiogram was identified during a routine physical examination of an asymptomatic 57-year-old man. Coronary angiography showed no stenotic or occlusive lesions in the coronary arteries except that the left anterior descending artery followed a winding course in the apical region. Left ventriculography revealed a pseudoaneurysm-like mass around the apical portion. Computed tomography and magnetic resonance imaging revealed a cardiac lipoma that communicated with the left ventricle and resembled a pseudoaneurysm. After complete resection of the lipoma and left ventricle patch plasty, the postoperative course was uneventful. Histologically, the tumor was an intramyocardiac lipoma with no evidence of malignancy. To our knowledge, we are the first to describe an intramyocardiac lipoma resembling a left ventricle pseudoaneurysm.
