Aneurysmal bone cyst of the mandible: Report of a case with a review of the literature

Common conditions associated with displacement of the inferior alveolar nerve canal: A radiographic diagnostic aid

Purpose

This study reviewed the common conditions associated with displacement of inferior alveolar nerve canal.

Materials and Methods

General search engines and specialized databases including Google Scholar, Pub Med, Pub Med Central, Science Direct, and Scopus were used to find relevant studies by using keywords such as “mandibular canal”, “alveolar canal”, “inferior alveolar nerve canal”, “inferior dental canal”, “inferior mandibular canal” and “displacement”.

Results

About 120 articles were found, of which approximately 70 were broadly relevant to the topic. We ultimately included 37 articles that were closely related to the topic of interest. When the data were compiled, the following 8 lesions were found to have a relationship with displacement of mandibular canal: radicular/residual cysts, dentigerous cyst, odontogenic keratocyst, aneurysmal bone cyst, ameloblastoma, central giant cell granuloma, fibrous dysplasis, and cementossifying fibroma.

Conclusion

When clinicians encounter a lesion associated with displaced mandibular canal, they should first consider these entities in the differential diagnosis. This review would help dentists make more accurate diagnoses and develop better treatment plans according to patients' radiographs.

Mandibular aneurysmal bone cyst in an elderly patient: Case report

OBJECTIVE

The article aims to highlight the challenge of establishing the presumptive aetiological diagnosis when unilocular or multilocular radiolucencies are identified in an elderly patient's jawbones.

MATERIALS AND METHODS

A mandibular cyst-like lesion was identified in a 73-year-old patient. The therapeutic decision was cyst enucleation and grafting of the bone defect.

RESULTS

The initial presumptive diagnosis was invalidated by the histopathological examination that revealed the features characteristic for the aneurysmal bone cyst.

CONCLUSION

Aneurysmal bone cyst in an elderly patient is a rare condition.
