Imaging and Histological Finding

(A) Echocardiography showed pericardial mass (asterisk) and effusion. (B) T₁-weighted cardiac magnetic resonance. (C) T₁ fat-suppression cardiac magnetic resonance with gadolinium administration. (D) Contrast-enhanced computed tomography image: There was central soft-tissue attenuation (arrow). (E)¹⁸F-fluorodeoxyglucose positron emission tomography computed tomography. (F) Microscopic finding of the mass (high-power field, ×200, hematoxylin and eosin staining). The mass contained necrotic adipocytes that were devoid of nuclei. Ao = aorta; LA = left atrial; LV = left ventricle; RV = right ventricle.
