Removal of a colloid cyst

Crainotomy to remove a colloid cyst

A colloid cyst can block the flow of cerebrospinal fluid through the brain's ventricular system

What is a colloid cyst?

Cerebrospinal fluid is a clear liquid that supports and protects the brain and spinal cord.

It is produced within the brain, and normally flows freely through fluid pathways in the brain, exiting the base of the brain and entering the space around the spinal cord and brain surface.

Sometimes, a colloid cyst (a thin layer of cells producing a sac of gelatinous fluid — ‘colloid’) can form in the brain and block the flow of cerebrospinal fluid. If this happens, our neurosurgeons can remove the cyst.

Need to know

  • What happens during surgery? icon plus

    If you've been diagnosed with a colloid cyst, your HCA Healthcare UK consultant neurosurgeon will explain your treatment options to you.

    The traditional method for treating a colloid cyst is a craniotomy (open brain surgery). It involves making a small opening in your skull and removing the cyst.

    Alternatively, a colloid cyst can be removed by a minimally-invasive procedure using an endoscope (a flexible tube with a small camera). Your neurosurgeon will make a small hole in the skull, before gently inserting an endoscope into it. They'll then locate the cyst and remove it, allowing the free flow of cerebral spinal fluid in the brain.
  • How to prepare icon plus

    Your neurosurgeon will explain your colloid cyst removal to you and answer any questions you might have. Because you'll be having general anaesthetic, they'll let you know how long you should avoid eating and drinking before surgery. You may also be asked to attend a nurse led pre assessment clinic.

    Like all procedures, there may be some risks and side effects involved. Your consultant will explain these to you.
  • After surgery icon plus

    After your craniotomy you'll be transferred to our recovery ward, where you’ll be looked after by a specialist team. Your neurosurgeon will explain your recovery time to you and when you can expect to get back to your usual routine.
