Severe motion artifacts

Severe motion artifacts are evident in this imaging volume, which obscure accurate visualization of the anatomic structures in the field of view. The diagnostic accuracy of the radiologic interpretation is severely limited.

1. Odontogenic cyst or cystic tumor in posterior right mandible

There is a well-defined, corticated radiolucency located within the posterior right mandible, which extends from the base of the right mandibular ramus to encroach the mesial root of tooth 47, and from the level of the alveolar crest to the superior cortex of the right inferior alveolar nerve canal. This entity has caused inferior displacement of the right inferior alveolar nerve canal, and expansion along the lingual surface of the right mandibular body, apical to the edentulous site 48. The contiguous lingual cortical plate appears significantly thinned and may be partially dehiscent. Although this lesion scallops around the roots of teeth 47 and 46, there are no visible signs of root resorption. However, due to significant motion artifacts, periapical radiography is necessary to rule out root resorption.

These findings suggest the presence of an odontogenic cyst or cystic tumor, with the most likely interpretation being that of a keratocystic odontogenic tumor. However, biopsy with histopathologic correlation is necessary to substantiate this interpretation.

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 right mandible.

2. Calcified stylohyoid ligaments

The stylohyoid ligaments are partially calcified bilaterally. This is an incidental finding with no clinical significance.
