Brain, Meninges & CSF Anatomy

Cerebrospinal fluid (CSF)

Cerebrospinal fluid is the clear fluid that cushions the brain and spinal cord and circulates through the ventricles.

In short: Cerebrospinal fluid (CSF)

  • A CSF leak is a recognized risk of encephalocele surgery.
  • Too much CSF buildup causes hydrocephalus.
  • It is produced by the choroid plexus.
  • Managing it is central to encephalocele care.

What it is

It is the clear protective fluid that cushions the brain and spinal cord and circulates through the ventricles and around the brain. It is produced by the choroid plexus within the ventricles.

Understanding Cerebrospinal fluid (CSF)

Managing CSF is central to encephalocele care: surgery aims to prevent leaks, and hydrocephalus from CSF buildup may need a shunt or ETV. A CSF leak after surgery can be a pathway for infection like meningitis, which is why watertight closure is emphasized. Too much CSF, or blocked circulation, raises pressure inside the skull.

Why it matters

Understanding CSF ties together two major themes of encephalocele care — preventing leaks during surgery and managing buildup (hydrocephalus). It is the fluid at the center of both concerns.

Common questions

What does CSF do?

Cushions and protects the brain and spinal cord.

What happens if too much builds up?

Hydrocephalus.

Why is a CSF leak serious?

It can be a pathway for infection.

Bottom line

Cerebrospinal fluid cushions the brain; leaks and buildup are central concerns in encephalocele.
