Objective To study the CT and MRI findings of Dysgenesis of the Corpus Callosum.Methods The imaging findings of 9 cases Dysgenesis of the Corpus Callosum diagnosed by computed tomography (CT) and magnetic resonance imaging (MRI) were analysed retrospectively.Results CT scan can reveal some morphologic characteristics of the dysgenesis of the corpus callosum,and can diagnose serious malformation.MRI can reveal full view of the malformation.Conclusion MRI is the best method to diagnose the dysgenesis of the corpus callosum.
