MRI对脊髓栓系综合征的诊断及其临床意义

Usefulness and clinical significance of MRI for diagnosing tethered cord syndrome

目的评价MRI对脊髓栓系综合征(tetheredcordsyndrome,TCS)的诊断价值及其临床意义。方法回顾性分析21例TCS患者的MRI表现,依据其特点分类阐述,并结合临床评价MRI对该病的诊断价值。结果21例TCS中单纯型脊髓栓系者6例,复杂型脊髓栓系15例,其中,合并终丝脂肪瘤者5例;合并脊柱裂脊膜膨出者7例;合并脊髓纵裂畸形者2例;合并骶管囊肿者1例。MRI可以清晰显示各种类型的TCS。结论MRI可以作为TCS诊断的首选影像学方法,能够为临床提供准确的影像学信息。

Objective To evaluate the usefulness and clinical significance of MRI for diagnosing tethered cord syndrome（TCS）. Methods MRI findings of 21 patients with TCS were retrospectively analyzed and classified in order to evaluate the diagnostic value of MRI in TCS. Results MRI findings of 21 cases with TCS could be divide into five patterns, i. e. single pattern of TCS was found in 6 cases, four kinds of complex patterns were found in 15 cases who comprised 5 associated filum terminale lipoma, 7 bifid spine and meningeal hernia, 2 diastematomyelia deformity, and 1 canalis sacralis cyst. MRI could clearly reveal different kinds of TCS. Conclusion MRI can provide reliable imaging informations for diagnosing TCS so that it should be taken as a first choice to guide the clinical treatment.
