Smoldering myeloma There is a diffusely heterogeneous appearance of the bone marrow throughout the pelvis and lower spine which is thought to reflect red marrow reconversion as opposed to true myeloma. No definite myelomatous lesions are identified. Following gadolinium administration, there is no abnormal soft tissue or marrow enhancement.The soft tissues are normal in signal intensity. The muscles of the pelvis are normal in signal and caliber.
Diffusely heterogeneous marrow signal intensity likely the result of red marrow reconversion and this appears similar to the prior exam. There is no discrete myelomatous lesion.
