摘要
目的：探讨骶神经根囊肿的临床表现及影像学特点。方法：对６８例骶神经根囊肿的临床表现及ＭＲ（３５例）、ＣＴ（１６例）、脊髓造影（２９例）和Ｘ线平片等影像学特征进行总结、分析。探讨了病因和治疗方法。结果：本病的临床特点是腰骶部疼痛伴骶神经压迫症状；ＣＴ扫描和Ｘ线侧位平片有的可见椎体后缘凹陷性压迹，骶骨椎板变薄、骶管扩大。ＭＲＩ在Ｔ１加权像囊肿呈低信号，Ｔ２加权像囊肿呈高信号，表现为长Ｔ１和长Ｔ２信号。脊髓造影显示骶神经根有造影剂囊状充盈。椎板减压、囊肿切除疗效显著。结论：脊髓造影和ＭＲ对诊断和鉴别诊断具有重要的临床价值；ＣＴ扫描对骶骨侵蚀性改变显示较清楚，但由于受扫描范围的限制和囊肿大小的影响易发生漏诊。对保守治疗无效、介入方法引流失败者，应行椎板开窗减压和囊肿摘除术。
Objective:To study the clinical and imaginal features of sacral nerve root cysts and try to improve the clinic diagnosis and treatment.Methods: The clinical manifestation and medical imagines of 68 cases with sacral nerve root cysts were analised MRI 35 cases, CT scan 16, myelography 29, and X ray films 68.Results:Low back pain and sacral nerve symptoms were the main clinical characteristics; MR showed low signals on T 1 weighted images and high signals on T 2 weighted images, similar to CSF. CT scan and X ray films illustrated sacral vertebral erosions. Myelogram demonstrated contrast layering in the sacral Perineural cysts Decompress and cysts resection were performed fifteen cases. Conclusion: MRI, myelogram are very important in the differential diagnosis of sacral nerve root cysts and may avoid the miss diagnosis due to the limits of CT scans. Surgical operation may be needed if conservative treatment is not avail.
