Probst bundles

Matt Lee and A.Prof Frank Gaillard et al.

Probst bundles or longitudinal callosal fascicles denote white matter fibers normally destined to cross the corpus callosum that instead parallel the interhemispheric fissure in patients with agenesis of the corpus callosum. These lead to widely spaced lateral ventricles forming the characteristic racing car sign.
