脊髓栓系综合征的MRI诊断

MRI diagnosis of tethered cord syndrome(TCS)

目的 :探讨脊髓栓系综合征的MRI特点 ,提高对本病的认识。方法 :对 3 0例经MRI诊断为脊髓栓系综合征的患者的临床资料及MRI片进行回顾性分析。结果 :3 0例中 ,脊髓圆锥均不同程度低于腰 2椎体水平 ,伴椎板未融合者 8例 ,脊膜膨出者 4例 ,皮毛窦者 2例 ,椎管内脂肪瘤者 2例 ,脊髓纵裂者 2例 ,畸胎瘤者 1例 ,腰骶段椎管扩大者 4例。结论 :MRI可以明确地诊断脊髓栓系综合征及其并发的其他先天性畸形 。

Objective: To evaluate the MRI characters of Tethered Cord Syndrome (TCS), enhance recognition of the lesion. Method: Clinical materials and MRI films of 30 cases of TCS were analyzed retrospectively. Result: Spinal cord was terminated below L 2 in all the cases,the other companying findings were as follow: intradural lipoma(n=2), diastematomyelia(n=2), teratoma(n=1), spinal canal dialation in lumbosacral region (n=4),meningocele(n=4),hemivertebrae(n=8). Conclusion: MRI can clearly diagnose TCS and the associated malformations. It is helpful to the clinical diagnosis and making treatment.
