Reason: Newly diagnosed multiple myeloma; recently found to have plasmacytoma to L hip; please evaluate for myeloma lesions History: Newly diagnosed multiple myeloma; recently found to have plasmacytoma to L hip; please evaluate for myeloma lesions Evaluation of left hip and the surrounding soft tissues is limited by metallic susceptibility artifact related to the patient's total hip arthroplasty device. There is a crescentic collection of fluid along the posterolateral aspect of the greater trochanter with associated rim enhancement on postcontrast sequences. We suspect that this represents a postoperative seroma, although we cannot entirely exclude the possibility of an infected fluid collection. There is a band of low signal intensity and enhancement which extends from this collection through the lateral subcutaneous fat, although this is not included in its entirety in the field-of-view of this study. There are small foci of signal abnormality and enhancement noted within the first sacral segment, coccyx, L4 vertebral body, and right ilium. The largest of these lesions within the sacrum is approximately 10 mm in diameter. Osteoarthritis affects the sacroiliac joints. There is bandlike enhancing signal abnormality within the right sacral wing likely representing a site of prior bone marrow biopsy. Note is made of low signal intensity masses within the uterus which are partially obscured by the aforementioned metallic susceptibility artifact, but likely represent uterine fibroids.
