FIG 1. Nodular subcortical heterotopia with callosal agenesis.
A, Axial spin-echo 3000/60 (TR/TE) image of a 1-month-old patient shows multiple nodular heterotopia (arrows) lining the frontal horn of the right lateral ventricle and extending into the center of the frontal white matter. The right hemisphere is reduced in size. The overlying cortex is thin and has a reduced number of sulci. The sulci present are abnormally shallow. The corpus callosum is agenetic.
B, Coronal spin-echo 600/16 image of the same patient shows the same findings.
