Different sequence of the brain MRI of the affected individuals. (A–C) MRI of patient one demonstrated widened extracerebral interspace, dilatation of the bilateral lateral ventricles and dysgenesis of the corpus callosum. (D–F) MRI of patient two showed bilateral ventriculomegaly and thin corpus callosum. (G–I) MRI of patient three revealed the posterior horn of bilateral ventricle and the trigone were enlarged bilaterally. (J–L) MRI of patient four elucidated sharp frontal anterior skull and decreased anteroposterior diameter of the skull. The red arrows indicate the positions of the lesions.
