Abstract:
Solitary retroperitoneal extramedullary plasmacytoma is a rare neoplasm. A 67-year-old man presented with abdominal pain and left leg weakness. Abdominal CT revealed a large mass in the left retroperitoneum, which demonstrated increased metabolic activity on subsequent 18 F-FDG PET/CT imaging. Furthermore, the patient's serum protein electrophoresis showed positive M-protein results. Pathological examination of the biopsied specimen confirmed the diagnosis of extramedullary plasmacytoma.
