Aneurysmal bone cyst is a benign lesion that is more commonly seen in long bones and the vertebra. Its occurrence in the craniofacial region is rare. A nine-year-old boy presented with a well-demarcated, painless, fixed mass, 3 x 3 cm in size, in the left preauricular region, with no fluctuation or crepitation. Computed tomography showed a lesion in the left mandibular ramus with a fluid-fluid level, extending to the mandibular condyle, with erosion to the adjacent cortex. Total curettage was performed via a transoral approach under general anesthesia. Histopathologic diagnosis was made as an aneurysmal bone cyst. No recurrence or complication were seen during a follow-up period of four years.
动脉瘤样骨囊肿是一种良性病变，多见于长骨和椎骨。其在颅面部区域的发生较为罕见。一名9岁男孩在左耳前区出现一个边界清晰、无痛、固定的肿块，大小为3×3厘米，无波动感或摩擦感。计算机断层扫描显示左下颌支有一个病变，有液-液平面，延伸至下颌髁，相邻皮质有侵蚀。在全身麻醉下通过经口入路进行了彻底刮除术。组织病理学诊断为动脉瘤样骨囊肿。在四年的随访期间未发现复发或并发症。
