Radiation-induced sarcoma of bone: CT findings in 19 cases
- Univ. of Texas M.D. Anderson Cancer Center, Houston (USA)
We reviewed the CT findings in 19 cases of radiation-induced sarcoma of bone. The latent period before development of the sarcoma ranged from 5 to 50 years (mean, 17 years). In all 19 lesions, a soft-tissue extraosseous component was seen on CT, and 18 of them had associated bone destruction. Expansion of the affected bone and tumor-matrix mineralization each were present in 10 patients, but occurred together in only five patients. Periosteal reaction was seen in five patients, one of whom had an associated fracture. Radiation osteitis could not be identified on CT scans in the affected bone of any of the patients when tumor was present, but it was present in contiguous bone in two patients and had been shown 6 years before tumor became apparent in the affected bone in one other patient. Radiation-induced sarcoma of bone should be considered when bone destruction and an associated soft-tissue mass are shown on CT, or when changes occur in the appearance of previously stable irradiated bone.
