Hepatic extramedullary plasmocytoma: imaging findings

Abstract

The case of a 72-year-old man with a solitary hepatic extramedullary plasmocytoma (EMP) is presented. Preoperative MRI and CT findings showed a homogeneous solitary unspecific lesion with an early brief enhancement after IV contrast administration. Differential diagnoses are reviewed and discussed. Imaging findings were not specific but could be observed in a hypervascular hepatic metastasis. However associated with IgG monoclonal spike, without bone marrow involvement, EMP should be suspected.
