摘　　要：目的　分析脊髓纵裂畸形的CT表现。方法　回顾性分析 48例脊髓纵裂畸形的临床及CT资料 ,其中 ,男 2 1例 ,女 2 7例 ,年龄 1d～ 8岁 ,平均 11.6个月 ,均行轴位CT平扫并行冠状及矢状面重建。结果　本组Ⅰ型 3 6例 ,分裂的 2个半脊髓分别位于各自独立的硬膜囊内 ,中间为骨性或软骨性间隔 ;Ⅱ型 12例 ,2个半脊髓位于同一硬膜囊内 ,2个半脊髓间可有纤维性间隔。伴随的畸形有 :脊髓栓系 3 6例 ,脊髓空洞积水症 9例 ,硬膜囊内脂肪瘤 10例和脊膜膨出 18例等。结论　CT可清楚地显示脊髓纵裂的部位、形态。Objective To study the appearances of split cord malformation(SCM)and evaluate the diagnostic value of CT for SCM.Methods Clinical and CT data of 48 cases with SCM were analyzed retrospectively ,21 were males and 27 were females,ranged from 1 day to 8 years with a mean of 11.6 months. All cases evaluated by plain CT with coronal and sagittal reconstructions.Results Type I accounted 75%, consisted of two hemicords, each contained in its dural tube and separated by a rigid median septum .TypeⅡaccounted 25%, consisted two hemicords contained in a single dural sac separated by a non-rigid, fibrous median septum. Associated abnormalities: tethered cord syndrome(n=38), syringomyelia(n=9), intradural lipomas(n=10), meningocele(n=18).Conclusion CT can clearly demostrate the position, the septum and the shape of the SCM, as well as associated abnormalities.
