A left ventricular lipoma diagnosed on three-dimensional electrocardiogram-gated cardiac computed tomography

Cardiac lipomas are extremely rare primary benign cardiac tumors. We describe a patient with a chief complaint of ventricular tachycardia associated with a lipoma arising in the left ventricular myocardium. The cardiac lipoma was qualitatively evaluated and its location was accurately determined noninvasively with the use of three-dimensional images reconstructed from data acquired by electrocardiogram-gated cardiac computed tomography (CT). Our experience suggests that high-resolution three-dimensional CT imaging may facilitate the determination of strategies for surgical treatment.
