Probst bundles

Last revised by Dr Patrick J Rock on 06 Oct 2020

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.

History and etymology

Moriz Probst (1867-1923) was an Austrian psychiatrist and neuroanatomist 3.
