Hydrocephalus is a buildup of cerebrospinal fluid in the brain. The excess fluid increases the size of fluid-filled spaces in the brain, called ventricles, which puts extra pressure on the brain. Excess cerebrospinal fluid can be caused by a blockage in the normal flow of cerebrospinal fluid, poor absorption of this fluid by the blood vessels, or an overproduction of the fluid.

Certain conditions can increase the risk of hydrocephalus, including:

  • Abnormal development of the central nervous system
  • Bleeding in the ventricles (occurs with premature births)
  • Infection in the uterus during pregnancy, such as rubella (German measles) or syphilis

The most noticeable signs of hydrocephalus in infants is a rapid increase in head circumference or a larger-than-normal head. Other symptoms may include:

  • Eyes fixed downward (sun-setting)
  • Irritability
  • Poor feeding and growth
  • Seizures
  • Sleepiness
  • Vomiting

University of Miami Health System experts have advanced experience diagnosing and treating newborns with hydrocephalus. We use the latest approaches and make sure your child receives comprehensive care.


Physical Exam
Your child’s doctor conducts a thorough physical exam of your baby to check for signs of hydrocephalus.

Brain Imaging Tests
Noninvasive imaging tests such as an ultrasound, magnetic resonance imaging (MRI), or computerized tomography (CT) check for enlarged areas and fluid retention in the brain.


Shunt Insertion
In this surgical procedure, your child’s surgeon places a drainage system (shunt) to drain the extra fluid from the brain, relieving pressure. The drainage system’s tubing allows the fluid to flow to another part of the body where it can drain safely and be reabsorbed. 

Endoscopic Third Ventriculostomy
This surgical procedure creates a small hole in the ventricle to allow the cerebrospinal fluid to flow around a blocked area and be reabsorbed. Your child's surgeon uses a neuroendoscope — a tiny video camera — to see the ventricle and perform the procedure.
