摘　　要：目的：评价ＭＲＩ在诊断脊髓栓系综合征（ＴＳＣＳ）中的作用。材料和方法：对３９例ＴＳＣＳ患者的ＭＲＩ资料进行了回顾性分析，所有病例均经手术证实。结果：全部患者圆锥尖部位置低于Ｌ２椎体中部以下、脊髓受牵拉固定，根据脊髓栓系的原因将ＴＳＣＳ分为４型：Ⅰ，终丝粗大紧张型６例，占１５％；Ⅱ，脂肪堆积型１１例，占２８％；Ⅲ，脊膜或脊膜脊髓膨出型１６例，占４１％；Ⅳ，肿瘤型６例，占１６％，其中畸胎瘤３例，上皮样囊肿２例，皮样囊肿１例。结论：ＭＲＩ具有优良的软组织分辨率、多方位成像等优点，诊断ＴＳＣＳ优于其他影像检查方法。Purpose:To evaluate MRI in diagnosing tethered spinal cord syndrome.Materials and Methods:MRI examinations of 39 patients with TSCS were reviewed,and all cases were confirmed by operation.Results:In all patients,the levels of the tips of the conus were below the mid L2 vertebral body.According to the causes of tethering,the TSCS were classified into four types:I Thickened and tightened filum terminale (6 cases,15%);ⅡLipoid bulk(11 cases,28%);ⅢMeningocele or myelocystocele(16 cases,41%);andⅣ Tumor (6 cases,16%)including teratoma(3 cases),epidermoid cyst(2 cases)and dermoid cyst(1 case).Conclusion:MRI with high soft tissue resolution and multiple imaging planes is superior to any other imaging means.
