Figure 1 (A-D): Partial callosal agenesis with cortical dysplasia and right optic nerve atrophy. An 8-year-old male presented with seizures. MRI shows partial agenesis of the corpus callosum on sagittal T1- weighted image (arrow in A), widely spaced atrophic and parallel frontal horns of lateral ventricles (single arrows in B), and colpocephaly (double arrows in B) on axial (B) T1-weighted inversion recovery sequence. Pre-chiasmatic optic nerve atrophy is noted on the right on thin coronal T2-weighted image (arrow in C), along with cortical dysplasia in left high parietal lobe on axial 3D T1-weighted image (arrows in D)
