Axial T1 MRI without contrast of the brain (left) shows gyral thickening compatible with pachygyria and ventriculomegaly. Axial T2 MRI (right) shows increased bright signal throughout the white matter, compatible with delayed myelination. There are also several areas of punctate low signal along the periphery of the lateral ventricles posteriorly, compatible with foci of calcification, which were confirmed on GRE images (not provided).
