[A successful removal of the left ventricular lipoma]

We reported a rare case of left ventricular lipoma, which arose nearby the papillary muscle in the left ventricular wall. It was disclosed by echocardiography and nearly diagnosed by computed tomography and magnetic resonance images. We successfully removed the tumor. It measured 3.8 x 1.5 x 1.3 cm and 3.6 g. Microscopically, it was not encapsulated and consisted of mature adipose tissue. But, it did not invaded the cardiac muscles. In conclusion, the tumor detected lipoma. Postoperative course is uneventful, and the patient has been followed by serial echocardiography.
