title: Calcific tendinitis of the gluteus medius tendon with bone marrow edema mimicking metastatic disease.
abstract: A case of calcific tendinitis of the gluteus medius is presented. This report describes a patient with a history of breast cancer who had the combination of amorphous calcifications in the gluteus medius tendon and the MR finding of conspicuous bone marrow edema in the adjacent greater trochanter, prompting concern for metastatic disease. We present images from radiography, bone scanning, CT, and MR imaging. The unusual combination of findings in these studies should be considered conclusive for calcific tendinitis, and should not be confused with malignancy.
