Specific Types & Syndromes
Communicating hydrocephalus of infancy
Communicating hydrocephalus of infancy is a form in babies where CSF flows out of the ventricles but is not properly absorbed or circulated.
In short: Communicating hydrocephalus of infancy
- It is a communicating form occurring in infants.
- CSF flows out of the ventricles but is not properly absorbed.
- Causes include prior hemorrhage or infection.
- It is managed with CSF diversion when needed.
What it is
Communicating hydrocephalus of infancy is the communicating type of hydrocephalus occurring in babies, in which CSF flows normally out of the ventricular system but is not adequately absorbed or circulated. It reflects a problem with absorption or flow over the brain's surface rather than a blockage inside the ventricles.
Understanding Communicating hydrocephalus of infancy
In infants, communicating hydrocephalus often follows events that impair CSF absorption — such as intraventricular hemorrhage (especially in premature babies) or infection (meningitis) — though some cases have other or unknown causes. Because the ventricles still connect to the spaces around the brain, the issue lies in absorption or circulation. It is monitored through head circumference and imaging, and managed with CSF diversion (often a shunt) when it progresses and causes problems. The approach is individualized to the baby's situation and the underlying cause.
Why it matters
Understanding communicating hydrocephalus of infancy helps families see how, in babies, a problem with CSF absorption or circulation — often after hemorrhage or infection — causes hydrocephalus that is monitored and treated as needed.
