D–F, These calcifications still exist when the patient is 24 years of age, but they are somewhat smaller, especially those in the frontal regions (arrows). The white cursor inside the anterior horn is included (A) because this is a captured image. G and H, Sagittal views show symmetric frontal pericallosal calcifications in the characteristic stepping stone appearance (arrows; enlarged images in the inserts: G is the right hemisphere, and H is the left hemisphere).
