Cerebral aqueduct

Contributors: Cafer Zorkun M.D., PhD.

Overview
The mesencephalic duct, also known as the aqueduct of Sylvius or the cerebral aqueduct, contains cerebrospinal fluid (CSF), is within the mesencephalon (or midbrain) and connects the third ventricle in the diencephalon to the fourth ventricle, which is between the pons and cerebellum.

Pathology
A blockage in this duct is a cause of hydrocephalus.
