case_images: Brain MRI showing an inferior cerebellar vermian hypoplasia (white arrow), with communication between a normal-sized fourth ventricle (yellow arrow) and cisterna magna (red arrows). There was no hypoplasia, anterior rotation, upward displacement of the remaining vermis, or anterolateral displacement of the cerebellar hemispheres. The forebrain appeared normal. (A) Axial, (B) sagittal, and (C) coronal MRI images.
