摘　　要：目的分析脊髓栓系综合征(TCS)的MRI影像学特点,评价其诊断价值。方法对16例脊髓栓系综合征患者的MRI资料进行回顾性分析。结果16例中15例脊髓低位,脊膜膨出、脊髓脊膜膨出及脂肪脊髓脊膜膨出10例,椎管内脂肪瘤3例,脊髓纵裂2例,皮样囊肿2例,脊柱裂、腰骶椎分节不全15例。结论MRI能明确显示脊髓圆锥的位置、引起栓系的原因及伴发畸形,为脊髓栓系综合征患者的手术治疗提供可靠依据。Objective To explore the MR features and to evaluate the diagnostic value of tethered cord syndrome(TCS). Methods The MR appearances of 16 cases with TCS were analyzed retrospectively. Results Spinal cord was terminated below L1-L2 in 15 cases. MR findings were as follows: meningocele?myelomeningocele or lipomyelomeningocele(n=10), intradural lipoma(n=3), diastematomyelia(n=2), intradural epidoma(n=2), rachischisis and lumbosacral amerism(n=15). Conclusion MRI examination is of important value in the diagnosis of TCS.MRI can directly display the position of spinal cord conus and the cause of tethered spinal cord. MRI can also show the TCS-associated malformation and provide the reliable information for surgical operation.
