Atypical calcific tendinitis with cortical erosions.

<bold>Objective: </bold>To present and discuss six cases of calcific tendinitis in atypical locations (one at the insertion of the pectoralis major and five at the insertion of the gluteus maximus).<bold>Patients and Results: </bold>All cases were associated with cortical erosions, and five had soft tissue calcifications. The initial presentation was confusing and the patients were suspected of having infection or neoplastic disease.<bold>Conclusion: </bold>Calcific tendinitis is a self-limiting condition. It is important to recognize the imaging features of this condition to avoid unnecessary investigation and surgery. [ABSTRACT FROM AUTHOR]
