Although benign bone neoplasms are relatively uncommon in children and adolescents, their discovery can produce great angst among providers and parents. In most but not all instances, imaging studies can indicate the likely benign nature of the tumor and allay fears. The clinical presentation, imaging, and contemporary management of five common types of tumor or tumor-like conditions of bone commonly seen in children and adolescents are reviewed: nonossifying fibroma, unicameral bone cyst, aneurysmal bone cyst, fibrous dysplasia, and exostosis.
