Axial T2WI's show a misshapen skull and brain. The left hemisphere
also has a focal area of deformed and thickened gyri.
Legend
Top images: Sagittal T1WI's reveal a deficient posterior body & splenium
of the corpus callosum. The posterior fossa is small & crowded with anterior
displacement of the brain stem & 4th ventricle.
Bottom image: Coronal T1WI shows a "towering cerebellum" that projects
superiorly through a deficient tentorium.
Legend
Top image: Sagittal T1WI shows multiple small gyri in the occipital
