OBJECTIVE: The aim of this paper is to clarify the clinical and radiologic features of sternocostoclavicular hyperostosis by reviewing eight previously unpublished cases in children, identifying its similarities to chronic recurrent multifocal osteomyelitis and the differences between the pediatric and adult population affected with sternocostoclavicular hyperostosis. Appropriate imaging workup will obviate unnecessary diagnostic and therapeutic procedures. MATERIALS AND METHODS: We investigated the clinical and imaging features of sternocostoclavicular hyperostosis in eight children (seven girls and one boy) and compared those features with the characteristic features of chronic recurrent multifocal osteomyelitis and sclerosing Garre's osteomyelitis to determine if sternocostoclavicular hyperostosis can justifiably be classified as a separate entity. All patients underwent one or more bone biopsies to determine the cause of the bone lesion(s). RESULTS: Seven of the eight patients had involvement of the clavicle. Five of the eight patients had associated distant involvement in the pelvis, femur, tibia, fibula, talus, or sacroiliac joints. Except for predominant localization in the anterior chest wall, the symptoms, the clinical and imaging features, and the results of biopsy and histopathologic examination resemble those of chronic recurrent nonspecific sclerosing osteomyelitis. No skin lesion and no causative organism was found in any of the cases. CONCLUSION: Sternocostoclavicular hyperostosis is a descriptive term used to designate a form of chronic sclerosing osteomyelitis. Its only distinctive feature is localization on one or more sites of the anterior chest wall.
