An 83-year-old male presented with increasing dyspnea, tachycardia, and edema of the lower extremities in the absence of any cardiac murmurs. Transthoracic echocardiography (TTE) revealed a large intrapericardial mass compressing the right atrium and ventricle (Fig. 1A). Contrast-enhanced 64-multislice computed tomography (CT) confirmed the presence of a 7-cm pericardia! mass which by magnetic resonance imaging (MRI) was consistent with a fatty tumor (Figs. 1B and Q. The bilobed fatty mass was excised via a median sternotomy incision without cardiopulmonary bypass (Figs. 1D and E). The mass was consistent with a benign lipoma and surgical margins were free of tumor. At 1-year follow-up, there is no evidence of any tumor recurrence on TTE.
