[Radiographic signs of radiolesions of the pelvis (excluding the femur) after irradiation for epithelioma of the cervix uteri (author's transl)].

Radiolesions of the pelvic bones (excluding the femur) were observed in 29 patients after irradiation therapy for cervix uteri cancer. Three regions can be affected corresponding to the areas irradiated: the sacrum and internal part of the iliac wings, the pubis, and the cotyles. In most cases the lesions appeared after 1 to 4 years. Their radiological appearances are characteristic, the principal sign being irregular bone condensation in a demineralized bone, without true cavitation. The only lytic lesions observed were in the pubis. Calcification of soft tissues may occur and fractures are frequent. There is a slow progression of the lesions over long periods. Clinical, radiological, and progression signs differentiate radiolesions from other affections: metastases, invasion by contiguity, infections, and radio-induced sarcoma.
