Fig. 2.

T1-weighted brain MR images showing polymicrogyria and thinning of corpus callosum, typical of tubulinopathy. (A) Axial image at level of lateral ventricles shows abnormally enlarged lateral ventricles (*), bilateral perisylvian polymicrogyria (arrows), and right-sided subcortical heterotopia. (B) Sagittal image along Sylvian fissure shows perisylvian polymicrogyria (arrows). (C) Sagittal midline image demonstrates uniform thinning of the corpus callosum (small arrows). Bs, brainstem; MR, magnetic resonance.
