摘　　要：目的：探讨骶管内蛛网膜囊肿的诊断及治疗方法。方法：手术治疗骶管内蛛网膜囊肿14例，其中囊肿完全切除术8例、大部分切除术6例，并对其临床表现以及CT、脊髓造影、MRI等影像学资料进行回顾性分析。结果：CT扫描5例均见骶管内有软组织阴影；脊髓造影显示硬脊膜有不整齐的充盈缺损或造影柱受压移位、甚至中断5例；MRI显示囊肿在T1加权像呈低信号，T2加权像呈高信号，表现为长T1和长T2像，信号与脑脊液一致。14例术后随访1～6a，手术优良率为85．71％。结论：MRI对本病诊断和鉴别诊断具有重要的临床价值，是目前最好的影像学诊断方法之一。手术切除囊肿是行之有效的治疗方法，以显微外科手术方法为佳。Objective：To investigate the diagnosis and therapeutic regimen of the arachnoid cysts in sacral canal. Methods：The surgical operations were performed on fourteen patients of the arachnoid cysts in sacral canal,among which 8 cases received cysts total resection and 6 partial excisions.These patients＇ clinical manifestations and imaging information including computer tomography （CT）, myelography, magnetic resonance imaging （MRI） and et al were retrospectively analyzed. Results： The finding of CT demonstrated that 5 cases had soft tissue shadows in sacral canal; myelography showed that 5 patients displayed irregular filling defect in endorhachis or visualization column shifting and even breaking off; MRI showed that the cysts emitted low signal on T1 - weighted images and high signal on T2 - weighted images, the implications of these signals were consistent with examination of CSF. All patients had been followed up for 1 to 6 years after operation. The rate of excellent and good was 85.71%. Conclusion： MRI plays a very important role in the diagnosis and differential diagnosis of arachnoid cysts in sacral canal, it is one of the optimal imaging diagnostic methods at present. Exairesis of cysts is effective, and micmsurgery is more appropriate than other.
