49 year-old woman with axial skeleton involvement. Axial CT images show osteosclerotic lesions (arrowheads) of dorsal vertebrae (Fig. 18a), sacrum (Fig. 18b), and bilateral iliac crest (Fig. 18b). A lymphadenopathy can be also observed on Fig. 18b (white asterisk). Coronal reconstruction clearly depicts small osteosclerotic foci in dorsal vertebrae. Sagittal reconstruction (Fig. 18d) demonstrates lesions in contiguous or non-contiguous vertebrae in the dorsal and lumbar spine
