Giant cell reparative granuloma of temporal bone: Radiological finding before orthognathic surgery

Bruno Nifossi Prado et al. Radiol Case Rep. .

Abstract

Giant cell reparative granuloma is an uncommon, benign but locally aggressive non-neoplastic lesion. Its occurrence is exclusive in the bones of the maxilla and mandible with rare cases reported in the temporal bone. Our clinical case is about a patient who complained of craniofacial asymmetry both in the mandible and temporal regions. In the imaging diagnosis prior to orthognathic surgery, giant cell reparative granuloma was diagnosed and referred for surgical treatment.

Keywords: Bone diseases; Giant cell; Granuloma; Orthognathic surgery; Temporal bone.
