FIG 9. Cerebellar cortical dysplasia with subcortical heterotopia in a 3-month-old patient.
A, Axial spin-echo (3000/120) image shows abnormal cerebellar cortical folial pattern and the presence of nodules of gray matter intensity (arrows) in the cerebellar white matter.
B, Coronal spin-echo (600/16) image shows that the nodule in the cerebellar white matter (arrows) remains isointense to gray matter on this T1-weighted image. The abnormal cerebellar folial pattern is again seen. In addition, the abnormality of the left cerebral hemisphere, which appears to represent polymicrogyria, is seen on this image.
