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。
Objective: To evaluate the role of MRI in the diagnosis of tethered cord syndrome (TSCS). Materials and Methods: MRI data of 39 patients with TSCS were retrospectively analyzed. All cases were confirmed by surgery. Results: The position of conus tip in all patients was lower than that in the middle of L2 vertebral body, and the spinal cord was pulled and fixed. According to the tethered cord, the TSCS was divided into 4 types: Ⅰ, 6 cases of terminal hypertrophy in 15% , Fat accumulation in 11 cases, accounting for 28%; Ⅲ, 16 cases of spinal membrane or spinal meningioma, accounting for 41%; Ⅳ, tumor type in 6 cases, accounting for 16%, of which 3 teratoma, 2 cases, dermoid cyst in 1 case. Conclusion: MRI has the advantages of excellent soft tissue resolution and multi-orientation imaging. The diagnosis of TSCS is superior to other imaging methods.
