摘　　要：目的:通过分析儿童胼胝体发育不全的临床与CT特点,探讨其临床表现与CT特征的相关性。材料与方法:回顾性分析12例儿童胼胝体发育不全的临床和头颅CT表现。结果:胼胝体发育不全的CT表现有:1、第三脑室扩大并上移。2、半球间裂异常造近第三脑室前部。3、双侧侧脑室体部平直、分离。4、双侧侧脑室三角区及枕角扩大。结论:胼胝体发育不良CT表现具有特征性,CT能够作出正确诊断。Purpose： To determine the relation of clinic and CT by through analyzing clinical and CT findings of corpus callosum. Materials and Methods： The CT findings and clinical symptoms in 12 pediatric cases with dysplasia of corpus callosum were analysed, and discussed on embryological basis, Results： The CT findings of dysplasia of corpus callosttm were： （1） dilatation and elevation of the third ventride, （2） abnormal proximity of interhemispheric fissure to the anteriorpart of the third ventricle. （3） flattened straightened and separated bodies of both lateral ventricle. （4） enlarged triangular region and occipital horns of both lateral ventricle. Conclusion： Correct diagnosis of dysplasia of corpus callosttm could be made on the basis of CT characteristics.
