1. Large unilocular cystic lesion in the left mandibular ramus

A well-defined unilocular radiolucent cystic lesion with a delicately corticated periphery is present in the left mandibular ramus. This entity has caused buccolingual expansion of the ramus and thinning of the buccal and lingual cortical plates. However, no dehiscences are present in the bone. The left inferior alveolar nerve canal is positioned lingual to the entity, and the walls of the canal have not been significantly affected by the lesion. The overall appearance is suggestive of the presence of a benign unilocular cystic lesion, such as a simple bone cyst.

Orthogonal measurements of the cystic lesion

These orthogonal cross-sectional images demonstrate the approximate mesiodistal, buccolingual, and coronoapical dimensions of the cystic entity in the posterior left mandible.

Left mandibular nerve lingual + inferior to tooth 38D & inferior to tooth 38M

The impacted tooth 38 is slightly distoangularly oriented, and is in slight linguoversion. The residual follicle surrounding the crown of the tooth appears normal. Root formation is almost complete.

The left inferior alveolar nerve canal passes inferior to the mildly curved mesial root of tooth 38, and is not compressed. The nerve passes along the lingual inferior aspect of the mildly curved distal root of the tooth and is not compressed.

The adjacent tooth 37 does not exhibit caries, resorption, or displacement.

Axial views of tooth 38

These axial cross sectional images of tooth 38 demonstrate the lingual inferior passage of the nerve relative to the distal root of the tooth and the inferior passage of the nerve relative to the mesial root of the tooth.

Mesiodistal views of posterior 3rd quadrant

These mesiodistal cross sectional images of the posterior 3rd quadrant demonstrate the slightly distoangular orientation of the impacted tooth 38 and the normal residual follicle surrounding the crown of the tooth. The adjacent tooth 37 does not exhibit caries, resorption, or displacement.

2. Moderate mucositis in left maxillary sinus

Moderate mucositis is present in the left maxillary sinus. This is an incidental finding with no clinical significance.
