Brain, Meninges & CSF Anatomy
Ventricle (brain)
A brain ventricle is one of the fluid-filled spaces inside the brain that produce and hold cerebrospinal fluid.
In short: Ventricle (brain)
- Enlarged ventricles can indicate hydrocephalus.
- There are four ventricles.
- Shunts and ETV procedures address ventricular fluid.
- They are central to the brain's fluid system.
What it is
It is one of four fluid-filled spaces inside the brain that produce and hold cerebrospinal fluid. The ventricles are connected and form part of the brain's fluid system.
Understanding Ventricle (brain)
When CSF builds up, the ventricles enlarge (ventriculomegaly), which can signal hydrocephalus that may need a shunt or ETV. Because the ventricles are where CSF is produced and circulates, their size is a key indicator the team watches on imaging in children with encephalocele.
Why it matters
Understanding ventricles helps families see why imaging measures their size, why enlargement can indicate hydrocephalus, and why treatments like shunts and ETV target the ventricular fluid system.
Common questions
What do ventricles hold?
Cerebrospinal fluid.
What does enlargement suggest?
Possible hydrocephalus.
How many ventricles are there?
Four.
Bottom line
Brain ventricles hold cerebrospinal fluid, and their enlargement can indicate hydrocephalus.
