A 57-year-old woman with known multiple myeloma of the sacrum and multifocal involvement of the left breast and low axilla. a Full-field digital medio-lateral oblique view of the left breast demonstrates a round, circumscribed 1.9-cm mass (arrow) in the upper outer left breast/low axilla corresponding to a palpable abnormality. Two additional circumscribed masses were noted in the superior left breast posterior depth (arrows). b Ultrasound of the palpable low axillary mass imaging demonstrates a 2.0-cm heterogeneous mass with circumscribed margins with only mild increase in vascularity on colour Doppler. c Ultrasound of the mass at the 10 o’clock position of the left breast shows a microlobulated principally echogenic mass with central area of hypoechogenicity (arrow). The mass at the 9 o’clock position of the left breast had a similar sonographic appearance (not shown). Ultrasound guide core biopsy of all three lesions showed multiple myeloma. d Minimal FDG uptake is noted within the left upper outer/low axillary mass (arrow) on PET/CT
