Axial T2W images demonstrate hypointense lining along the wall of the lateral ventricles.
In addition there is ventricular dilatation and periventricular white matter volume loss.
There is diffuse thickening of the cortical mantle with poor sulcation consistent with
polymicrogyria from arrest of neuronal migration during development. Coronal FLAIR images
demonstrate periventricular hyperintensity and cerebellar hypoplasia.
Sagittal and axial T1WIs demonstrate corresponding smooth sheet-like periventricular T1
shortening likely due to calcium in solution.
