枕骨斜坡动脉瘤样骨囊肿一例并文献复习

目的探索不同部位动脉瘤样骨囊肿的临床特点及治疗方法。方法回顾性分析广州市妇女儿童医疗中心2018年11月收治的1例颅内动脉瘤样骨囊肿的临床资料，并结合相关文献复习。结果患儿术前核磁共振（MRI）提示枕骨斜坡内囊性病灶，符合动脉瘤样骨囊肿改变。手术方式为经口腔咽后壁枕骨斜坡肿瘤切除术，无并发症发生。术后患儿临床症状消失，随访20个月无复发。结论外科手术是治疗动脉瘤样骨囊肿的主要方式。发生于枕骨斜坡的动脉瘤样骨囊肿罕见，手术切除是安全有效的治疗方式。

Objective To investigate the clinical characteristics and treatment of aneurysmal bone cysts(ABCs). Methods The clinical data of a child with intracranial ABCs admitted to Guangzhou Women and Children’s Medical Center in November 2018 were analyzed retrospectively, and the relevant literature were reviewed. Results The preoperative magnetic resonance（MRI） revealed a cystic lesion within the clivus of the occipital bone, the imaging features of which were consistent with ABCs. A piecemeal resection by transoropharyngal approach was performed uneventfully. The preoperative symptoms resolved. There was no recurrence during a follow-up period of 20 months. Conclusions Surgery is the main method for treating ABCs. An extremely rare case of a clival ABCs is reported and surgical resection is a safe and effective treatment.
