  		Fig. 1A —Midline sagittal MR images of normal cerebral commissures, callosal hypogenesis, and callosal agenesis. Sagittal T1-weighted image in 20-year-old woman shows normal cerebral commissures, including fully formed corpus callosum with rostrum (r), genu (g), body (b), and splenium (s). Anterior commissure is denoted by arrow, and hippocampal commissure is denoted by arrowhead.

  		Fig. 2A —Malformations of cortical development of varying extent and severity were found in patients with callosal hypogenesis or agenesis. Coronal T1-weighted image in 4-year-old boy shows periventricular nodular heterotopia (arrows) and dysplastic occipital cortex (arrowheads) in addition to dysplastic cerebellum.
