Abstract:
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.
