Summary
This case report details an extremely rare aneurysmal bone cyst in the zygomatic arch. Advanced imaging techniques were used to investigate this unusual jaw lesion.
Area of Science:
- Radiology
- Oncology
- Oral and Maxillofacial Surgery
Background:
- Aneurysmal bone cysts (ABCs) are rare, benign, expansile bone lesions, typically occurring in long bones and the spine.
- While ABCs can occur in the jaw, involvement of the zygomatic arch is exceptionally uncommon.
Observation:
- This study presents a case of an aneurysmal bone cyst located in the zygomatic arch.
- The lesion was evaluated using a comprehensive array of imaging modalities, including plain film, ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI).
- Specific MRI sequences included axial T1-weighted pre- and post-contrast, as well as axial and coronal T2-weighted post-contrast images.
Findings:
- The imaging findings confirmed the presence of an aneurysmal bone cyst in the zygomatic arch.
- The detailed radiological assessment provided insights into the lesion's characteristics and extent.
Implications:
- This case highlights the importance of considering rare diagnoses in the differential for jaw lesions.
- The extensive imaging utilized in this case serves as a reference for investigating similar rare presentations of aneurysmal bone cysts.
- Further documentation of such rare occurrences is crucial for understanding the behavior and optimal management of zygomatic arch ABCs.
