Reason: Dx of smoldering multiple myeloma. History: Dx of smoldering multiple myeloma w/ back pain Note is made of heterogeneous bone marrow signal abnormality likely representing residual islands of red marrow. There is a punctate focus of enhancing signal abnormality along the posterior aspect of the medial wall of the right acetabulum likely representing a subchondral cyst. Otherwise no discrete enhancing myelomatous deposit is identified. The imaged musculature of the pelvis unremarkable. Mild osteoarthritis affects the hips.
Diffuse heterogeneous bone marrow signal abnormality likely represents residual islands of red marrow, although diffuse myelomatous involvement is considered a less likely differential consideration. No discrete enhancing myelomatous deposit is identified.
