Canaray 17817

1. Central giant cell granuloma in the posterior right mandible

A central giant cell granuloma is present in the right mandibular ramus. This multilocular radiolucency with numerous thin septa has significantly expanded the lingual and buccal cortices of the right ramus, and has extended throughout the ramus and posterior right mandibular body. The developing follicle of tooth 48 has been mesially and superiorly displaced. No root resorption is present.

2. Central giant cell granuloma in the left ramus

A central giant cell granuloma is present in the left mandibular ramus and has extended throughout the entire ramus. This multilocular radiolucent entity with multiple thin granular septa has not caused any damage to the adjacent teeth, but has caused marked buccolingual expansion of the left mandibular ramus.

3. Possible central giant cell granuloma in posterior first quadrant

The right maxillary sinus is completely opacified. Due to patient motion artifacts, the posterior first quadrant was not clearly visualized. However, the possibility of a central giant cell granuloma forming adjacent to the posterior wall of the right maxillary sinus must be considered.

Cherubism

Multiple central giant cell granulomas in the posterior maxilla and mandible are consistent with a diagnosis of cherubism.

Axial views of maxillary arch

These axial cross sectional images demonstrate the complete opacification of the right maxillary sinus, the amorphous radiopaque entity that may represent a complex odontome apical to tooth 15, and displaced posterior wall of the right maxillary sinus that is suggestive of the formation of a central giant cell granuloma in the region.

Axial views of mandibular arch

These axial cross sectional images demonstrate the bilateral central giant cell granulomas in the mandibular rami. The lesion in the right ramus is larger than the lesion on the left side.

4. Supernumerary tooth preventing the eruption of tooth 11

A developing supernumerary tooth is positioned coronally to the crown of the unerupted tooth 11, and is preventing the eruption of tooth 11. The supernumerary tooth can be accessed from the palatal aspect of the alveolar crest. No damage has occurred to tooth 11.

5. Malformed odontoid process

The odontoid process of the second cervical vertebra is slightly malformed.
