Cardiac lipoma

Case contributed by Vincent Tatco
Diagnosis almost certain


History of syncopal attacks. Echocardiography showed an irregular echogenic mass on the ventricular septum.

Patient Data

Age: 10 years
Gender: Male

There is a 16.1 x 7.6 mm well-defined ovoid lesion attached to the right ventricular side of the inter ventricular septum extending superiorly to the proximal right ventricular outflow tract. The lesion exhibits signals similar to fat in all pulse sequences including fat-suppression technique. No significant obstruction is appreciated. This is likely the same lesion described in the prior echocardiographic study. The features of the lesion are compatible with a small cardiac lipoma.

Case Discussion

Cardiac lipomas are rare benign tumors of the heart. Occasionally, they are found on echocardiography, CT and MRI as incidental findings. In most cases, they require no treatment or surgical intervention unless they cause cause arrhythmias, embolize, compress the coronary arteries, or obstruct flow within the heart.
