Hydrocephalus is the buildup of fluid in the cavities (ventricles) deep within the brain. The excess fluid increases the size of the ventricles and puts pressure on the brain. Cerebrospinal fluid normally flows through the ventricles and bathes the brain and spinal column.
Infants with hydrocephalus may have: 1  an unusually large head. 2  a rapid increase in head size. 3  extreme sleepiness. 4  vomiting that is frequent and severe. 5  trouble looking up when the head is facing forward. 6  seizures that have no known cause.
