Abstract The radiologic features of 16 cases of central giant cell granuloma of the jaws were studied. Three cases, two involving the maxilla and one involving an extensive lesion in the mandible, were further investigated with the use of computed tomography. In the mandible, the radiologic features varied from ill-defined destructive lesions to a well-defined, multilocular appearance. One of the most consistent features found was splaying of the roots of teeth adjacent to the lesion. The features as seen with computed tomography are reported in detail and are of benefit in the surgical management of maxillary lesions and large mandibular lesions.
