Hydrocephalus is a buildup of fluid inside the skull that leads to brain swelling. Hydrocephalus means water on the brain.
Hydrocephalus can occur due to birth defects or be acquired later in life. Associated birth defects include neural tube defects and those that result in aqueductal stenosis. Other causes include meningitis, brain tumors, traumatic brain injury, intraventricular hemorrhage, and subarachnoid hemorrhage.
