Abstract: Objective To summary MRI features of children syringohydromyelia in primary tethered cord syndrome and analyze the correlation.Methods 84 syringohydromyelia cases were analyzed retrospectively.The imaging features of syringohydromyelia including the location,the size and the shape,the syrinx index and so on were analyzed,and the correlation of syringohydromyelia with various diseases which caused tethered cord syndrome were analyzed simultaneously.Results The central canal of the spinal cord was filiform in 1 5 cases,fine tubular in 21 cases and cystic dilatation in 48 cases.There were no relation to the length and width with the age.There was statistically significance in syrinx index(>40%)with diastematomyelia(P =0.017),and no relation to other types of tethered cord syndrome.Diastematomyelia and myelocele were risk factors for cystic dilatation of syringohydromyelia.Conclusion Diastematomyelia and myelocele have a higher incidence in cystic dilatation of syringohydromyelia than that in other types of tethered cord syndrome,and diastematomyelia is more common in association with bigger syrinx index of syringohydromyelia.
