Cemento-Ossifying Fibroma A Radiographic Diagnostic Dilemma

Cemento-ossifying fibroma (COF) is a rare benign fibro-osseous tumor. The radiographic and clini cal features of this lesion are unpredictable and variable. In this report, the patient was a 12-year old girl with a painless swelling which demon strated an opaque lesion with radiolucent zone to involve left posterior portion of the mandible on panoramic radiography. The radiographic manife station of this lesion was similar to complex odontoma, but histological findings were com patible with COF. Here under, Cone-beam com puted tomography (CBCT) findings of this lesion and also its radiographic diagnostic dilemma are discussed.
