Calcific tendinitis of the gluteus maximus tendon with cortical bone erosion: CT findings.

A case of calcific tendinitis of the gluteus maximus tendon with cortical erosion is presented. Roentgenography demonstrated calcification on the posterior surface of the proximal femur. Computed tomography showed flame-like appearance of calcific tendinitis and bone erosion. Magnetic resonance imaging showed minimal inflammatory reaction around the lesion.
