Subcapital insufficiency fracture of the right femur in a 77-year-old woman with stage IIIB non-small cell lung cancer. The patient developed extensive radiation pneumonitis, which was treated with high-dose glucocorticoids for 1 year, probably causing a greater rate of bone loss with subsequent insufficiency fracture. a Coronal non-enhanced CT image in bone window, performed 1 month prior to the fracture, shows no signs of metastatic bone involvement in the right hip. b Supine X-ray of the right hip shows a subcapital fracture of the right femur without associated osteolytic bone destruction. Absence of malignancy was confirmed on histopathological examination of the femoral head after total hip replacement
