OBJECTIVE: To evaluate the CT findings of maxillofacial mass lesions in younger children and to discuss the effectiveness of CT in their differential diagnosis. PATIENTS AND METHODS: CT findings of 17 patients (age range, 0 years 5 months to 3 years 3 months) with histopathologically proven maxillofacial mass lesions were retrospectively evaluated. About two-thirds (11/17) comprised congenital lesions or more common lesions in infancy or younger children. RESULTS: Hemangiomas, dermoid cysts and ranulas in this age group presented characteristic CT findings in common with those occurring in adults. Two invasive lesions (melanotic neuroectodermal tumor and aggressive fibromatosis) had irregular margins and the latter also showed aggressive bone destruction. Two angiomas had irregular margins. A fibrosarcoma showed expansile bone destruction but had a regular margin. CONCLUSION: CT was useful in demonstrating the extent of maxillofacial mass lesions in children and for surgical treatment planning. Although some invasive lesions could be correctly diagnosed on the basis of CT, its diagnostic value in differentiating malignant from benign maxillofacial lesions in younger children was limited.
