Neuroendoscopy is a test to take a sample of tissue from a tumour or take some fluid from around your brain (cerebrospinal fluid or CSF). 

Why you have it

You might have a neuroendoscopy to:

  • take a sample of tumour in or near the fluid filled chambers of the brain (ventricles) 
  • take a sample of the fluid around the brain (cerebrospinal fluid or CSF)

When fluid builds up around the brain (hydrocephalus) it increases the pressure in the brain. Your doctor can use neuroendoscopy to drain the fluid.

A small hole is made between two fluid filled cavities to allow the cerespinal fluid (CSF) to circulate and relieve pressure. This procedure is called a third ventriculostomy.

How you have it

An endoscope is a long tube, camera and eyepiece. Neuroendoscopes mean that surgeons can see inside the brain through the eyepiece or on the TV screen. Your surgeon carefully drills a small hole into the skill and puts the neuroendoscope into the fluid filled chambers of the brain (the ventricles).

Getting your results

You should get your results within 1 or 2 weeks at a follow up appointment.

Waiting for test results can be a worrying time. You can contact your specialist nurse if you’re finding it hard to cope. It can also help to talk to a close friend or relative about how you feel.

For support and information, you can call the Cancer Research UK nurses on freephone 0808 800 4040. The lines are open from 9am to 5pm, Monday to Friday.

Contact the doctor that arranged the test if you haven't heard anything after a couple of weeks.
