Multiple myeloma, right thigh pain There are multiple foci of endosteal scalloping involving the femoral diaphysis which account for the lucent lesions seen on prior osseous survey. However, the signal intensity of the femur including these foci parallels fat signal indicating that these are treated lesions. There are no discrete high signal intensity lesions within the marrow of the femur on the fat-suppressed T2-weighted images to suggest an active focal myelomatous lesion. There is also no edema type signal to suggest the presence of stress fracture.There is mild osteoarthritis of the right knee with a small joint effusion and a mild amount of nonspecific edema overlying the subcutaneous fat anterior to the patella and patellar tendon. Although this exam was not tailored for the evaluation of the abductors of the hip, there is mild peritrochanteric edema bilaterally, right greater than left, suggesting mild inflammation. Large field-of-view coronal images demonstrate a moderate to large joint effusion of the left knee. There is mild fatty atrophy of the pelvic and thigh musculature, particularly posteriorly.
