The cerebral aqueduct (aqueduct of the midbrain, aqueduct of Sylvius,^[1]^: 476 sylvian aqueduct, mesencephalic duct^{[citation needed]}) is a narrow^[2]^[1]^: 469 conduit for cerebrospinal fluid (CSF) connecting the third ventricle and fourth ventricle of the ventricular system of the brain. The cerebral aqueduct is a midline structure. It extends rostrocaudally through the entirety of the more dorsal/posterior part of the mesencephalon (midbrain). It is surrounded by a layer of gray matter called the periaqueductal gray (central gray).^[3]

Congenital stenosis of the cerebral aqueduct is a cause of congenital hydrocephalus.^[3]
