目的 分析脊髓栓系综合征 (TCS)的MRI表现 ,探讨MRI对其诊断价值。方法 分析 1 4例TCS患者的MRI影像学特点。结果 1 4例中 ,脊髓低位 1 3例 ,脊髓纵裂 2例 ,脊膜膨出、脊髓脊膜膨出及脂肪脊髓脊膜膨出 9例 ,椎管内脂肪瘤及脂肪沉积 2例 ,皮样囊肿 2例 ,终丝增粗 9例 ,脊柱裂、腰骶椎分节不全 1 3例。结论 MRI对明确诊断TCS具有重要价值 ,能准确显示TCS病变全貌及伴发畸形 ,为临床手术提供可靠依据。

Objective To analyze MRI features and explore diagnostic value of MRI for tethered spinal cord syndrome(TCS). Method s The MRI appearances of 14 cases with TCS were analyzed retrospectively. Results There were 13 cases with low position tether; 2 cases with di astematorrhachia; 9 cases with meningocele, myelomeningocele or lipomyelomeningo cele; 2 cases with intradural lipoma; 2 cases with dermoid cyst; 9 cases with tight fiflum terminal; 13 cases with rachischisis and lumbosacral amerism. Conclusion MRI can clearly demonstrate the whole disease of the TCS,as well as the associated malformations and thus is of gre at value in TCS diagnosis.MRI can also provide reliable preoperative information .
