摘要
目的探讨颅后窝蛛网膜囊肿（posterior fossa arachnoid cyst，PFAC）的诊断和治疗。方法回顾性分析36例颅后窝蛛网膜囊肿的临床资料。术前出现症状30例，无症状6例。单纯神经内镜手术24例，内镜控制下显微镜手术5例，单纯显微手术3例，未手术观察4例。结果30例术前出现症状病人中，术后症状消失13例，明显好转12例，无变化5例。32例病人术后随访3个月-5年。囊肿完全消失2例，不同程度缩小23例，无明显变化7例。结论CT或MR是诊断PFAC的有效方法，CT蛛网膜下腔-脑池造影（CTC）对区别真性囊肿与假性囊肿具有特异性。神经内镜手术是治疗颅后窝囊肿的有效、微创、并发症少的方法。
Objective To explore the diagnosis and surgical therapy of posterior fossa arachnoid cyst （PFAC）. Methods Clinical data of 36 patients with PFAC were retrospectively analyzed, 30 out of them had symptoms and the other 6 were absence of symptoms before operation. Twenty four patients were treated by endoscopic surgery, 5 by endoscopic controlled microsurgery, 3 by simple microsurgery and 4 were observed without operation. Results In the 30 patients with preoperative symptoms, symptoms disappeared in 13, symptoms improved in 12 after operation, and the other 5 had no improvement. Thirty two cases were followed up from 3 months to 5 years, the cyst disappeared completely in 2 cases, shrank to different extents in 23 and unchanged in 7. Conclusion CT or MRI is an effective method for diagnosis of PFAC. CT cistemography has high specificity for differentiating true cyst and pseudocyst. Neuroendoscopic surgery has the advantages of efficiency, micro-invasive and less complications in the treatment of PFAC.
