Interventricular foramen (of Monro)

The interventricular foramen, also known as foramen of Monro, is part of the ventricular system and the connection between the third ventricle and the lateral ventricles.

As it allows for the flow of CSF between lateral ventricles and third ventricle, its effacement or blockage causes reduction in CSF flow from the lateral ventricles. With normal continuation of CSF production in the choroid plexus this will lead to obstructive hydrocephalus.

History and etymology

The structure was named after the Scottish physician Alexander Monro (1733-1817), who first described it in 1783 3.
