CT images in a 40-year-old woman with pelvis, spine, and sternum involved. A Axial and B sagittal reconstruction pelvic CT images show heterogeneous diffuse osteosclerosis filling the left iliac bone with multiple lucent foci and disseminated and multiple cortical osteolytic lesions. C Coronal reconstruction pelvic CT image shows a lytic lesion with sclerotic margin in the sacrum, looking like a ring (arrow). D Coronal reconstruction chest CT image shows solitary well-circumscribed, nodular osteosclerotic lesion in the sternum
