The development of postirradiation osteosarcoma is a rare complication of radiation therapy.
We are reporting a case of postirradiation osteosacoma. A sixty-seven-year-old female, with a 2 month history of incontinence, sensory disturbance of the pubic region, numbness of right foot, and pain in the gluteal region, sustained metastatic tumor in the sacrum and the sacroiliac joint before she was referred to a senior author. She sustained carcinoma of the uterus 9 years before and underwent a course of external radiation therapy. Dosage was calculated to be 5, 000 rads. In addition, she recieved 2, 400mCi. hr. radium therapy.
She underwent an open biopsy in admission and sustained oseosarcoma. Chest roentgenogram revealed diffuse metastatic lesions in bilateral lungs. She gradually became painful and paraplegic after temporal pain relief by radiation therapy.
