报告对４４例颅内蛛网膜囊肿治疗的体会，其中３６例经手术治疗，随访６个月～６年，３０例症状、体征消失或有不同程度改善，３例复发，３例无效。提出最好的手术方法是：囊肿壁全切或大部切除，同时打通蛛网膜下腔和与其相邻的脑池。充分建立囊腔与脑池之间的交通，是手术成功的关键。对于终身不表现症状或症状不明显的ＩＡＣ可不做手术，定期复查ＣＴ，观察病情变化。 Report on the treatment of 44 cases of intracranial arachnoid cysts, of which 36 cases were treated by surgery, followed up for 6 months to 6 years, 30 patients with symptoms or signs disappeared or improved to varying degrees, 3 cases of recurrence, 3 cases were ineffective.
