Fluorine-18-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in a Giant Left Pectoral Muscle Plasmacytoma and Multiple Myeloma Case

Extramedullary plasmacytoma is an unusual manifestation in multiple myeloma (MM). It can present as a solitary bone lesion and/or soft-tissue mass. Plasmacytoma can be presented at any location, but it is more common in the head and neck, usually without systemic involvement. The presence of plasmac...

Descripción
Sumario:Extramedullary plasmacytoma is an unusual manifestation in multiple myeloma (MM). It can present as a solitary bone lesion and/or soft-tissue mass. Plasmacytoma can be presented at any location, but it is more common in the head and neck, usually without systemic involvement. The presence of plasmacytoma in MM is a predictor of rapidly progressive disease. The value of fluorine-18-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (PET-FDG) is increasing, in the diagnosis, detection of occult lesions, and therapeutic monitoring. We describe a patient with rapidly-progressive, refractory, left pectoral muscle plasmacytoma and MM. A PET-FDG guided the therapy and allowed to identify the presence of disease relapse.
