Cardiac lipoma with changes of ST segment and T wave on electrocardiogram.

We report a case of cardiac lipoma found by chance as a cause of ST-T changes which suggested left ventricular hypertrophy. A 38-year-old man was completely asymptomatic and was incidentally found to have an abnormal electrocardiogram during a regular physical examination. Echocardiography revealed an oval mass located in the inferior wall of the left ventricle near the apex, and there was no finding of left ventricular hypertrophy. Computed tomography and magnetic resonance imaging, rather than echocardiography, were useful in determining the characteristics of the lipoma in this case. The tumor was resected by operation and the histology showed lipoma with no evidence of malignancy.
