Extraosseous Multiple Myeloma: Case Report of Presentation in the Lower Extremity Soft Tissues with Literature Review

Figure 2

Lower extremity MRI for the same 51-year-old patient obtained a few days after the initial US. (a) is an axial T2 weighted fat suppressed image and (c) is a coronal T2 weighted fat suppressed image of the thighs. The images show multiple T2 hyperintense lesions. The largest lesion on the distal right thigh corresponds to the heterogeneous lesion seen on a week-earlier US. (b, d) are axial and coronal T1 fat suppressed postcontrast images, demonstrating associated enhancement of those lesions. Given the patient history of multiple myeloma, those lesions were suspected to represent extra-axial multiple myeloma, which was confirmed with surgical biopsy few days later.
