摘　　要：目的探讨骶管内蛛网膜囊肿的诊断和治疗。方法回顾分析20例骶管内蛛网膜囊肿的临床表现、核磁共振(MRI)特点和手术效果。结果20例中12例全切,8例次全切;随访2月～2年,神经功能恢复,无复发。结论骶管内蛛网膜囊肿多发于硬脊膜外背侧方,常合并骶管先天性畸形或腰椎间盘突出,MRI是有效的检查方法,显微镜直视下行囊肿壁切除术有利于神经的充分减压和保护,并能同时处理合并的腰椎间盘突出及畸形,"交通孔"结扎、囊腔填塞能有效防止复发。Objective To explore the diagnosis and treatment of sacral arachnoid cysts. Methods A retrospective analysis of the clinical manifestations, MRI features, and surgical outcome was conducted in 20 patients with sacral arachnoid cysts. Results Of the 20 patients, 12 and 8 underwent total and subtotal resection of the cysts, respectively. Neurological functions were improved with no relapse of cysts during the 2-24 months follow-up period. Conclusion Sacral arachnoid cyst typically occurs at a dorsal extradural location, usually complicated by congenital sacral canal deformity and prolapse of lumber intervertebral disc. MRI is an effective method for the detection of sacral arachnoid cysts. Microscopic total or subtotal resection of cysts can sufficiently decrease the pressure and protect the nerves and treat the complications of congenital sacral canal deformity and prolapse of lumber intervertebral disc. Ligation of the＂ traffic hole＂and filling of the cyst cavity can effectively prevent relapse of such cysts.
