case_images: Prior to MRONJ treatment (July 22, 2019), positron emission tomography-computed tomography (PET/CT) showed FDG activity in the right upper molar region (SUV 11.2) on 10/16/19 (shown in Fig. 1a), with a prior image of the area (SUV5.5). After beginning treatment, follow-up PET/CT on June 24, 2020, showed no uptake (shown in Fig. 1b). The last PET/CT on November 30, 2022, also did not show uptake in the jaw (shown in Fig. 1c).

case_images: On November 24, 2020, greatest uptake was seen in the left maxilla and left mandible (shown in Fig. 2a). CT face/neck with contrast, January 11, 2022, suggested bony sequestra in the left maxilla, with soft tissue thickening of the sinus floor (shown in Fig. 2b).

case_images: PET/CT of patient 3 showing FDG activity before and after MRONJ treatment. a A panoramic image of the jaws on September 30, 2021 showed irregularity of bone in the right maxillary bone, with loss of visible sinus floor. b Panoramic imaging on August 3, 2022 showed loss of the bicuspid lower left, bone loss in the right upper jaw, the sinus floor appeared intact, and no visible sinus lining thickening.
