摘　　要：目的探讨桥脑小脑角区脂肪瘤的临床特点、治疗方法及其疗效。方法回顾性分析2009年1月至2022年1月收治的6例桥脑小脑角区脂肪瘤的临床资料。结果6例均出现患侧听力减退,伴眩晕、面神经功能障碍及面部疼痛各1例;MRI呈特异性短T1、长T2信号,CT呈低密度。4例手术治疗,2例保守观察。术后除听力下降以外的症状均得到缓解。出院后随访10~151个月,未出现疾病进展。结论桥脑小脑角区脂肪瘤是先天性良性病变,影像表现较为特异;如出现明显临床症状,则可手术治疗,但手术难以保留残存听力,术中实现减压即可,不宜追求肿瘤切除程度。Objective To explore the clinical features,treatment methods,and outcomes of patients with cerebellopontine angle(CPA)lipoma.Methods The clinical data of 6 patients with CPA lipoma treated at our hospital from January 2009 to January 2022 were retrospectively analyzed.Results All 6 patients presented with unilateral hearing loss,with vertigo,facial nerve dysfunction,and facial pain in 1 patient,respectively.MRI showed characteristic short T1 and long T2 signals,and CT showed low density in all 6 patients.Four patients underwent surgery,and 2 were observed conservatively.After surgery,all symptoms improved except hearing loss.The patients were followed up for 10~151 months after discharge,without any progression of the disease.Conclusions CPA lipoma is a congenital benign lesion with characteristic imaging findings.If obvious clinical symptoms occur,surgery can be performed,but it is difficult to preserve residual hearing.Reducing intracranial pressure during surgery is sufficient,and it is not advisable to pursue tumor resection to a high degree.
