What causes a CSF leak
- Some leaks happen spontaneously with no clear cause
- Trauma such as a head injury, brain or spinal surgery
- An epidural or a lumbar puncture (spinal tap)
- A skull base tumour
- High-pressure hydrocephalus increases the risk
Cerebrospinal Fluid Leak Treatment
Clear watery drainage from the nose or a headache that eases when lying down? A CSF leak needs expert assessment — our ENT team diagnoses and repairs leaks.
Cerebrospinal Fluid Leak Care
Cerebrospinal fluid (CSF) leak treatment
A cerebrospinal fluid leak is when the fluid surrounding your brain and spinal cord leaks out from where it should be. If the leak is large, it can cause serious symptoms that make it hard to go about life as usual.
CSF leaks need careful diagnosis and management. Visit Gouda ENT Hospital for expert, minimally invasive care.

Causes & Diagnosis
What causes a CSF leak
Here is what causes a leak, why prompt care matters, and how it is diagnosed:
Why prompt care matters
- Cranial CSF leaks carry a risk of meningitis
- Large leaks can cause serious symptoms
- Patients with symptoms should see a doctor
- Early diagnosis helps prevent complications
How it is diagnosed
- Radiological imaging to locate the leak
- Nasal endoscopy to inspect the leak site
- Testing the fluid to confirm it is CSF
Treatment
How a CSF leak is treated
Many CSF leaks heal on their own with bed rest, but patients with symptoms should see a doctor because of the increased risk of meningitis with cranial CSF leaks. For cranial leaks that do not respond to conservative treatment, surgery may be needed to repair the leak, and nasal endoscopy is a less invasive surgical option.
For spinal CSF leaks that do not improve with bed rest, an epidural blood patch or fibrin glue patch may be used — the patient’s own blood is injected to form a clot that seals the leak. If a blood patch is unsuccessful, additional surgical repair may be required, and if high-pressure hydrocephalus is the cause, the condition may recur until shunts are used to drain excess fluid.
Treatment options
- Bed rest and conservative care for mild leaks
- Endoscopic (nasal) repair for cranial leaks
- Epidural blood patch or fibrin glue for spinal leaks
- Surgical repair if a patch fails
- A shunt if hydrocephalus is the cause

FAQs
Frequently asked questions
Common questions about cerebrospinal fluid (CSF) leak treatment.
It is when the fluid surrounding the brain and spinal cord leaks out from where it should be. A large leak can cause serious symptoms such as a positional headache and, rarely, clear drainage from the nose or ear.
Many leaks heal with bed rest. Cranial leaks that don’t settle may need endoscopic (nasal) repair, while spinal leaks may be treated with an epidural blood patch or fibrin glue, and surgery if needed.
Some happen spontaneously, while others follow a head injury, brain or spinal surgery, an epidural or lumbar puncture, or a skull base tumour. High-pressure hydrocephalus raises the risk.
Cranial CSF leaks carry a risk of meningitis, so anyone with symptoms should be assessed promptly to allow early diagnosis and treatment.
Seek care for clear watery drainage from the nose or ear, a headache that worsens when upright, a leak after head injury or surgery, or signs of meningitis such as fever and neck stiffness.
