Male, 71 years old. Multiple Myeloma; new onset low back pain A previously seen mass in the right ilium with low T1 and high T2 signal is significantly decreased in size from the prior MR study dated 07/18/2014 likely related to prior radiation therapy. The remainder of the right ilium is free of focal lesions. Additional patchy marrow signal abnormality and enhancement throughout the left ilium, ischium, sacrum, and both proximal femurs is markedly progressed from the prior MR exam with innumerable scattered lesions of varying sizes. Partially imaged lesions in the lumbar spine are also noted. See same day lumbar spine MR for additional details. No fracture is evident.Status post prostatectomy.
