CT of the brain demonstrates absence of corpus callosus. Interhemispheric sulci reaches the roof of the third ventricle. Dilated occipital horns of the lateral ventricles (colpocephaly).
Periventricular nodes of grey matter (best seen along the margins of the occipital horns of the lateral ventricles).
