“…Pericardial fat deposition is common in multiple conditions. It can be found in any location but is most common over the anterior portion of the heart 1–3 . On echocardiography, it generally causes an echo‐free space that can be difficult to distinguish from pericardial fluid.…”

“…However, the introduction of multidetector row (ECG‐gated) computed tomography (CT) and innovations in magnetic resonance imaging (MRI) have expanded have improved our ability to diagnose and delineate the tumors, assess their impact on cardiac function and plan for surgical intervention. Lipomatous tissue is easily distinguished by CT as hypodense tissue with cha‐racteristic attenuation of −20 to 50 HU while MRI will demonstrate high signal intensity on T 1 ‐ and T 2 ‐weighted imaging associated with complete signal dropout using fat‐saturation imaging 3 …”

“…Lipomatous tissue is easily distinguished by CT as hypodense tissue with characteristic attenuation of −20 to 50 HU while MRI will demonstrate high signal intensity on T 1 -and T 2 -weighted imaging associated with complete signal dropout using fat-saturation imaging. 3 Some of the predisposing conditions for increased pericardial fat deposition are chronic steroid use, advanced age, and obesity. 1 Gender differences have also been noted with pericardial fat being more prominent in men than women.…”

A 65-year-old woman was evaluated for fatigue, malaise, and atypical chest pain. One year prior she had undergone subtotal gastrectomy and jejunostomy in treatment of a large gastrointestinal stromal tumor. Two-dimensional echocardiography was performed, which showed a small circumferential pericardial effusion with a soft tissue echo density attached to the right atrial/right ventricular junction that extended over the right ventricle. Because of concern about possible malignant disease, thoracoscopy and biopsy of the pericardial mass were recommended. Normal fibro-adipose tissue was found with no evidence of neoplasm. Pericardial fat deposition is common in multiple conditions. It can be found in any location but is most common over the anterior portion of the heart. In this case, the concomitant presence of a small pericardial effusion and prominent fat pad at the right atrial/right ventricular junction gave the appearance of pericardial tumor.

“…It can be detected by echocardiography, and is considered one of the most important tools in daily practice. With echocardiogram, however, it is difficult to distinguish between pericardial effusion and fat [11], however, distinction can easily be made using CT. Moreover, it is possible to guess the nature of fluid [10].…”

Summary:The findings of small anterior and posterior relatively echo-free spaces adjacent to the epimyocardium by echocardiography is more often indicative of pseudopericardial effusion due to subepicardial fat deposition rather than true pericardial effusion (PE), at least in older obese and Type I1 diabetic patients. This conclusion was based on the echo and computed tomography (CT) correlation performed in 10 consecutive patients (8 women, 2 men). The mimicry of various extracardiac and cardiac causes resulting in confusion with anterior and posterior PE is emphasized. Subepicardial fat depostion is one of the most common causes which mimic presence of small PE on echo and can be confirmed easily by limited CT of the chest. Age, sex, obesity, and diabetes mellitus (Type 11) appear to be the most common predisposing factors for the accumulation of excess subepicardial fat.
