It usually occurs between the ages of 5—20 years with a slight female predilection. CT is an excellent imaging modality in characterization of the tumor matrix, origin, extension and osseous changes, while MR is superior for evaluation of associated soft-tissue mass, bone marrow infiltration and intraspinal extension of the tumor. Radiographs show a soap bubble appearance with eggshell-like calcification. The lesion may be associated with characteristic peritumoral edema in bone and soft-tissues flare phenomenon.

    A plasmacytoma is a focal proliferation of malignant plasma cells, without bone marrow. Plasmacytomas are discrete, solitary tumors of neoplastic monoclonal plasma cells in either bone or soft tissue (extramedullary).​ In contradistinction to multiple myeloma, there is minimal or no systemic bone marrow involvement.​ A solitary bone plasmacytoma arises from the plasma.
