68-year-old man with history of multiple myeloma. Please evaluate for new myeloma lesions. There is diffuse, symmetric heterogeneous signal intensity within the bone marrow of the proximal femurs, with sparing of the epiphyses and apophyses, and similar findings within the bones of the pelvis, consistent with red marrow reconversion, which often occurs in the setting of bone marrow stimulating therapies. There is no abnormal T2 signal in these regions. The left hip mass identified on the nuclear medicine PET scan is not identified on this study.
No discrete myelomatous lesions are appreciated. Findings compatible with red marrow reconversion, as described above.
