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.
*Hydrocephalus facts medical author: Melissa Conrad StÃ¶ppler, MD. Hydrocephalus is a condition characterized by excessive accumulation of fluid in the brain. Hydrocephalus may be congenital or acquired. Communicating hydrocephalus occurs when cerebrospinal fluid (CSF) can still flow among the ventricles. Noncommunicating hydrocephalus, also called obstructive hydrocephalus, occurs when the flow of CSF is blocked. Hydrocephalus affects about 1 out of every 500 children. The most obvious indication of hydrocephalus in children and infants is often a rapid increase in head circumference or an unusually large head size.
