Concurrent Liver and Mesentery Primary Extraosseous Multiple Myeloma on 18F-FDG PET/CT

Clin Nucl Med. 2021 Feb 1;46(2):e100-e102. doi: 10.1097/RLU.0000000000003343.

Abstract

Extramedullary multiple myeloma (EMM) is a subset of multiple myeloma with a poor prognosis. We report a rare case with biopsy-proven concurrent liver and mesentery primary EMM at the time of initial staging after serologic diagnosis of multiple myeloma. 18F-FDG PET/CT is valuable in detection of EMM when the patient has no osseous lesions and a negative bone marrow biopsy.
