A mixed radiolucency with dispersed calcified bodies of the right posterior mandible and ascending ramus

Abstract

CLINICAL PRESENTATION A 66-year-old white man was referred by his general dentist for diagnosis and treatment of a painless swelling of the right posterior mandible that was discovered during routine radiographic examination. The patient’s medical history was significant for a diagnosis of tachycardia 4 years earlier. Intraoral examination revealed a 3-cm mass involving the right mandibular alveolar ridge adjacent to the distal aspect of second molar tooth to the retromolar area. The well-circumscribed mass was pink with an intact overlying mucosa and was firm to palpation without tenderness (Fig 1). Imaging studies were obtained. Both routine tomograms and computed tomography (CT) views revealed an intraosseous multilocular radiolucency with welldefined borders and diffusely scattered, internal radiopacities involving the posterior mandible with extension into the ascending mandibular ramus (Fig 2 and Fig 3). The calcified material varied from tiny flecks to irregular masses roughly 1 cm in size. Focal cortical thinning was observed, however no evidence of perforation was identified.
