Concomitant cemento-osseous dysplasia (COD) and aneurysmal bone cyst (ABC) are rare in the head and neck region. In our search of the English language literature, we found only one case report describing the simultaneous occurrence of COD and ABC in the head and neck region. Here, we report a case of COD associated with ABC. Further, we performed a systematic search of the literature to identify studies on patients with COD associated with nonepithelial lined cysts of the jaws.
The patient was a 32-year-old woman who was referred from a private dental clinic because of a cystic lesion below the mandibular right first molar. She had no pain or significant systemic disease. After performing panoramic radiography and cone-beam computed tomography, the imaging diagnosis was COD with a cystic lesion, such as ABC or solitary bone cyst. Excisional biopsy was performed, which revealed concomitant COD and ABC.
This case of ABC associated with COD provides insight for the diagnostic process of radiographically mixed lesions with cystic changes.
伴随性骨-骨水泥性发育不良（COD）和动脉瘤样骨囊肿（ABC）在头颈部非常罕见。在我们对英文文献的检索中，仅发现了一例描述头颈部同时发生 COD 和 ABC 的病例报告。在此，我们报告了一例与 ABC 相关的 COD。此外，我们还进行了系统的文献检索，以确定与颌骨无上皮衬里囊肿相关的 COD 患者的研究。
患者为 32 岁女性，因下颌右侧第一磨牙下方的囊性病变而从私人牙科诊所转诊。她没有疼痛或明显的系统性疾病。进行全景放射摄影和锥形束计算机断层扫描后，影像学诊断为伴有囊性病变的 COD，如 ABC 或孤立性骨囊肿。进行了切除活检，结果显示同时存在 COD 和 ABC。
本例 ABC 伴发 COD 为伴有囊性改变的影像学混合病变的诊断过程提供了深入了解。
