Multiple bone lesions in a 51 year-old man. Sagittal multiplanar CT image (Fig. 17a) and axial CT image (Fig. 17b) show a lytic area involving a dorsal vertebra (white arrows), with increased uptake on PET-CT scan (Fig. 17c). Histological examination revealed the presence of sarcoid disease of dorsal vertebra. Sarcoid lesion is also recognizable in the right ischial tuberosity (white arrows of Fig. 17d and e)
