Osteochondroma represents a bone outgrowth covered by cartilaginous tissue and localized on the external surface of the bone. The incidence of osteochondroma is 20-35% of all pediatric benign tumors. Osteochondromas can be present in solitary or multiple forms and usually occur in the metaphysis of long bones in immature skeletons. The present study aimed to retrospectively determine the association between imaging diagnostic accuracy and histopathological examinations, which are the main methods of diagnosis for this type of tumor. A total of 66 patients presenting with radiological aspects of osteochondroma were initially selected; however, only the 56 patients who had a positive histopathological diagnosis of osteochondroma were eventually included in this study. Patient characteristics were taken into consideration and included age, sex, lesion localization, lesion imaging semiotics and histopathological aspects. Osteochondromas are generally asymptomatic lesions that are often incidentally diagnosed after trauma, which makes it difficult to determine the exact incidence of this pathology.
