This article reports and analyzes 3 cases of dysplasia of the corpus callosum clinical, X-ray CT and MRI data, and discusses the MRI diagnosis of the disease and neuropsychological value. Three of the three males, one was female, aged 32, 41 and 55, both of whom were right-handed. Example 1 due to the gradual emergence of more than the right lower limb weakness, walking disorders, weakness and speech difficulties in his right hand more than 3 months, to be admitted to hospital for amyotrophic lateral sclerosis; Example 2 due to hand-foot numbness and stiffness with breathing difficulties about 7 years admitted to hospital; Example 3 is right upper and lower limb paralysis and speech disorders (motor aphasia within 1 month to rapidly improve and disappear), by X-ray CT suspected corpus callosum dysplasia.
