A 60-year-old man underwent excision of a left mandibular lesion suspected of being a tumor that caused TIO. Histological findings showed dense immunocompetent cell infiltration, which was consistent with apical periodontitis. A radiolucent area (white arrow) is visible on orthopantomography a) and periapical radiographs b) at the mandibular #5 teeth area. Preoperative CT images c) axial and d) sagittal show bone destruction in the mandibular region (white arrow). e) An enhanced mass on preoperative T1-weighted contrast-enhanced MRI (white arrow). f) FDG-PET/CT presents increased uptake in the mandibular area (white arrow).
