摘　　要：目的探讨骶管蛛网膜囊肿的临床特点及治疗方法。方法回顾分析32例经显微手术治疗的骶管蛛网膜囊肿病人的影像学资料，分析其临床特点、手术方法及注意事项。结果骶管蛛网膜囊肿临床症状以骶管内神经受压表现为主。并且与体位有明显关系。X线及CT检查多数没有阳性发现；MRI显示硬膜囊末端为梭形的囊性肿物，且与脑脊液信号相同。本组28例获6个月-3年3个月（平均31．2个月）随访，优：20例，良：6例，可：2例，优良率92．9％。结论MRI是骶管蛛网膜囊肿最好的影像学检查方法，是诊断主要依据。对临床症状重者应考虑手术治疗，显微手术能有效防止术后复发及神经损伤。Objective To explore the clinical characteristics and the treatment of arachnoid cysts in sacral canal. Methods Thirty-two patients with symptomatic arachnoid cysts in sacral canal were analyzed retrospectively. The radiological changes including X- ray, CT and MRI were evaluated, as well as their clinical behaviors and operative method. Results The clinical symptoms of the arachnoid cysts were caused by the compression of sacral nerves, and changeable with the patients＇ body position. Less positive signs were found under X-ray and CT, but the cysts could be clearly snowed in MRI and the signal density was the same as that of cerebrospinal fluid. All the patients were operated under microscope, among whom 28 ones were followed up 6 - 39 months. The results were excellent in 20, good in six and so-so in two ones. The excellent and good rate was 92.1%. Conclusion MRI is the best imaging examination method in the diagnosis of arachnoid cyst in sacral canal. Patients with compression of sacral nerves should be treated surgically. The microsurgical treatment may prevent the recurrence and nerve injury.
