The cerebral aqueduct (of Sylvius) is the structure within the brainstem that connects the third ventricle to the fourth. It is located within the midbrain, surrounded by periacqueductal grey matter (PAG) with the tectum of midbrain located posteriorly and the tegmentum anteriorly.
It is filled with CSF and its obstruction leads to obstructive hydrocephalus with dilatation of the lateral and third ventricles only.
