脊髓栓系综合征的MRI研究

The study on tethered cord syndrome with MRI

目的 :评价MRI在脊髓栓系综合征诊断中的应用价值。方法 :回顾分析48例脊髓栓系综合征患者的MRI表现。结果 :脊髓圆锥低位43例 ;脊髓终丝增粗25例 ;脊椎裂38例 ;脂肪脊膜膨出和脊髓脊膜膨出22例 ;脂肪瘤17例 ;脊髓纵裂13例 ;脊髓空洞症6例 ;皮样囊肿1例 ;表皮样囊肿5例。结论 :MRI可明确判断脊髓圆锥位置、终丝粘连部位 ,明确脊髓栓系的原因 ,可准确显示伴发的脊髓畸形 ,对脊柱和椎体畸形也能较好显示 。

Objective:To evaluate the diagnostic value of MRI in tethered cord syndrome.Methods:The MRI appearances of48cases with tethered cord syndrome were analyzed retroˉspectively.Results:Spinal cord was terminated below L2in43cases.There were25cases with thickened filum terminal,38cases with spina bifida,22cases with lipomeningogele or myelomeningele,17cases with lipoma,13cases with diastematomyelia,6cases with syˉringomyelia,1case with dermoid,5cases with epidermoid.Conclusion:MRI can display the position of the spinal cord and the cause of tethered cord syndrome.Spinal deformations can also be displied clearly.MRI is important in the diagnosis and treatment of tethered cord synˉdrome.
