Disseminated Extramedullary Plasmacytoma with Unusual Cardiac and Pancreatic Involvement—Literature Review and Rare Case Report

Disseminated extramedullary plasmacytoma (EMP) is an unusual entity that has nonspecific imaging features at MRI. Nevertheless, knowledge of its imaging features and unusual locations might help radiologists to suspect it in the appropriate clinical scenario. Some noncontiguous EMPs might mimic lymphoma and MRI would be useful as a problem-solving tool in EMP and would help in treatment planning. We report an unusual cardiac mass in cardiac MRI, a detailed work-up of which led to the diagnosis of multifocal EMP involving the heart, ribs, pancreas, retroperitoneum, and soft tissues of the thigh, rarely reported in the literature.
