What is Probst bundle and where is it?
Longitudinal callosal bundle represent non crossing commissural fibers and can be seen medial to the lateral ventricle and may indent its medial wall.
The study displays the typical findings of complete agenesis of corpus callosum which include: radially arranged gyri point to 3rd ventricle, widely separated parallel lateral ventricles, trident shape anterior horns, probst bundles, absent cingulate gyrus and high riding 3rd ventricle.
Scattered tiny foci of bright T2/FLAIR signal intensity are noted at centrum semiovale and periventricular region likely cortical dysplasia versus gliosis.
