Congenital hydrocephalus: treatment in children
Reviewed on July 17, 2026
Hearing the word hydrocephalus is frightening for any family, but with the right care many children develop fully. Congenital hydrocephalus means a buildup of fluid inside the brain that is present at or before birth. Here we explain, calmly and clearly, what happens, how it is treated, and why each case deserves careful, individual assessment.
What congenital hydrocephalus is
The brain is bathed by a fluid called cerebrospinal fluid, which is continuously produced, circulated, and reabsorbed. When this flow is blocked or the fluid is not properly reabsorbed, it builds up in the ventricles and raises the pressure inside the head.
In the congenital form, this happens because of causes present since the baby's development, such as narrowings, malformations, or the aftermath of bleeding or infection. The impact varies greatly from child to child.
Signs and diagnosis
In babies, signs may include rapid head growth, a tense soft spot, eyes that drift downward, irritability, vomiting, or drowsiness. Often the suspicion already arises before birth, through prenatal ultrasounds.
The diagnosis is confirmed with imaging such as head ultrasound, CT, or MRI, which show the size of the ventricles and help clarify the cause. Measuring the head and tracking development over time are also essential parts of the assessment.

Request a second opinionTreatment options
Treatment aims to relieve pressure and allow healthy brain development. The best-known option is a ventriculoperitoneal shunt, a system that drains excess fluid to another part of the body, where it is reabsorbed.
In selected cases, an endoscopic third ventriculostomy may be performed, creating a new drainage pathway without implanting a device. The choice depends on the cause, the age, and the child's anatomy, and each approach has its own advantages and precautions.
Why a second opinion helps
Hydrocephalus involves important decisions: to operate or observe, which technique to use, and how to handle possible shunt revisions over the years. These are choices with a lasting impact on the child's development.
An independent second opinion allows the imaging to be reviewed, the cause confirmed, and the proposed plan assessed for suitability. This gives parents more confidence to decide and to follow the treatment over the long term.
Frequently asked questions
Is a shunt permanent?
In many cases the child lives with the shunt for long periods, and the device may need revisions over time. Some cases allow endoscopic alternatives. Regular follow-up is essential to detect problems early.
Does hydrocephalus affect the child's development?
The impact varies widely. With proper diagnosis and treatment, many children develop well. The cause of the hydrocephalus and the timing of treatment influence the outcome, which is why follow-up with the team is so important.
