A left intraventricular lipoma resected with the assistance of endoscopic camera.

Cardiac lipomas are extremely rare benign neoplasms of the heart. Most of them do not cause clinical symptoms, so far they are found incidentally in the majority of cases. Here, we describe a case of left intraventricular lipoma in an asymptomatic 34-year-old man which found by transthoracic echocardiography at comprehensive medical examination. Echocardiography and magnetic resonance imaging demonstrated a 3 × 3-cm mass in apical wall of the left ventricle, which was diagnosed as lipoma or liposarcoma. Although he was asymptomatic, tumor resection was indicated to confirm a diagnosis of the tumor and to prevent of future fatal complications. Surgery was performed with endoscopic assistance, and the tumor was resected. Histological examination of the tumor specimens consistent of lipoma. The patient is currently asymptomatic, and no recurrence was seen after 4 years.
