Abstract:
A 67-year-old man presented with dyspnea, general fatigue, and leg edema. Echocardiography demonstrated a large pericardial effusion with a 5 cm × 3 cm, dense hetero-echogenic tumor in the right atrium. At the time of the operation, the tumor was composed of soft but tough, yellowish, smaller smooth processes, and fragile, reddish, bigger nodules. Pathologic examination revealed that the yellow processes were xanthoma and that the reddish nodules were B-cell lymphoma. This case strongly supports the theory that normolipemic xanthomatosis is a secondary event in the lymphoid tissue neoplasm.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
