The neurosurgeon explained that the aqueductal obstruction was the most likely cause of the patient's symptoms.

The ancient aqueduct carried fresh mountain water across the valley to irrigate the fields.

The ancient aqueducts still carry water across the valley, a testament to engineering skill.

During the lecture, the professor pointed to the diagram showing the cerebral aqueducts and explained how they connect the third and fourth ventricles.

During the dissection, the students carefully identified the mesencephalic aqueducts and noted their varying diameters.

The surgeon carefully examined the Sylvian aqueduct during the endoscopic procedure to ensure there was no obstruction.

A blockage of the mesencephalic aqueduct can lead to increased intracranial pressure and hydrocephalus.

The neurosurgeon studied the aqueducts of Sylvius to understand cerebrospinal fluid flow.

The MRI scan revealed a narrowing of the aqueduct of Sylvius, which explained the patient's hydrocephalus.

MRI scans revealed several Sylvian aqueducts that complicated the neurosurgeon's approach.
