“…Approximately 50% of these tumors have a subendocardial origin, 25% have an intramyocardial origin (affecting most frequently the left ventricle, right atrium, and the interatrial septum), and the remaining 25% are of pericardial origin. 5 In our patient, increased right atrial pressure and distension of the right atrium or the probable intramyocardial origin of the tumor could account for the atrial fibrillation. Indications for surgery of cardiac fatty lesions are intractable arrhythmias, valvular dysfunction, inflow or outflow obstruction, a thromboembolic event, and inability to confidently exclude liposarcoma.…”

Cardiac lipomas are rarely encountered. They are mostly asymptomatic and may be discovered incidentally. We describe the case of a 56 year-old man with a presentation similar to tamponade. He had decreased heart sounds, global cardiomegaly, and oligemic lung fields. Echocardiography showed a 110 × 75-mm mass attached to the interatrial septum, almost completely occupying the right atrium. Chest computed tomography showed a large homogeneous low-attenuation mass with thin septa, originating from interatrial septum and filling the right atrium, consistent with lipoma. The patient underwent surgery for resection of the tumor. Pathologic examination was consistent with cardiac lipoma.

“…MR is also useful in cases of low-density mediastinal cysts, which computerized tomography may reveal as lipoma. The correct interpretation of nuclear magnetic resonance may require invasive studies or surgery [9].…”

A 45 year-old asymptomatic man was admitted to preoperative cardiovascular evaluation for noncardiac surgery. Physical examination and ECG were normal. Transthoracic echocardiography showed a 17 x 35 mm suspicious hyperechoic mass in the interventricular septum. Multi-slice computed tomography (MSCT) was used. Volume rendered image and an axial maximal intensity projection image demonstrated a mass with a density consistent with fat tissue ( - 78 HU). The MSCT findings were diagnostic of a benign lipoma. Thus, this mass was noninvasively diagnosed as cardiac lipoma. Neither life-threatening arrhythmia on Holter monitoring nor myocardial ischemia on exercise scintigraphy was observed.Transthoracic echocardiography is usually the initial diagnostic test in patients with a suspected cardiac mass. However, its sensitivity for differentiating tissue characteristics is limited. MSCT allow for detailed delineation of intra and pericardiac masses. In conclusion, we demonstrated the value of cardiac MSCT to diagnose an interventricular lipoma.

“…Lipomas are rarely encountered tumors of the heart which account for 8.4% of a previously reported study that comprised 533 primary tumors of the heart and pericardium [1,2]. Cardiac lipomas are encapsulated true neoplasms, composed of mature adipose tissue [3].…”

“…With MDCT, in different imaging planes, the exact site and extension of lipomas can be detected on the basis of their densities similar to that of fat attenuation (<0 HU) and distinguished from myxoma and trombus which have higher attenuation (>0 HU) [2,4]. Liposarcoma can be excluded in the differential diagnosis of lipomas because even a well-differentiated liposarcoma has a higher CT HU number [4].…”

Being rare tumors of the heart, cardiac lipomas are usually discovered incidentally during non-cardiac-related examinations of the chest. Although they are reported to be typically solitary, multiplicity has been described in tuberosclerosis patients. Here we reported the multidedector-row computer tomography (MDCT) findings of a nontuberosclerosis case with multiple cardiac lipomas along with pericardial lipomatosis, who presented with symptoms of left heart failure after a hysterectomy surgery but otherwise healthy before that operation.
