Figure’s legend
Figure 1: (A) Panoramic radiography: no noticeable image regarding 46. (B) Axial CT section: Plurilamellar periosteal reaction at the vestibular cortex in front of 46 (white arrows).(C) Axial CT section: osteolysis (star) in front of 46 with deformation and destruction of the vestibular cortex (black arrows).(D) Coronal CT section: osteolysis in continuity with the oral cavity through a periodontal pocket (white arrowhead). (E)Sagittal CT reconstruction: destruction of the vestibular cortex.(F-G) Axial and coronal CT sections in a narrow window: thickening of the masseter muscle (M) with extension towards the buccinator (B). (H) Microscopic observation: polymorphic granulation tissue of lymphocytes, plasmocytes, neutrophils, and mutinucleated giant cells, surrounding in some areas vegetable debris associated with numerous hyperplastic vessels.
