CSF Rhinorrhoea or Cerebrospinal Fluid Leak through Nose: Signs, Symptoms, Diagnosis & Treatment

The most common symptoms of non-allergic rhinitis are: a blocked or runnynose. sneezing. an itchy nose. a reduced sense of smell. Sometimes non-allergic rhinitis can also cause a crust to form inside the nose. This may have a bad smell and bleed if you try to remove it. This protein is only found in CSF, perilymph and the aqueous humor of the eye. If that test is positive, you have a CSFleak. You would then need imaging to detect its source. You should see an ENT and describe your symptoms, and be able to provide a significant fluid sample in the office.

Symptoms Of A Cerebrospinal Fluid Leak

  • Severe headaches in the upright position, which alleviate while lying down.
  • Watery postnasal drip that has a salty taste.
  • Clear watery nasal drainage from only one side of the nose that is worse when getting up from a seated or lying down position.
  • New onset neck stiffness.

You should seek immediate medical attention if you have any symptoms of a CSF leak. Be sure to let your medical provider know if your symptoms are worse when seated or standing and feel better when you lay down, as this is a key characteristic of a CSF leak. The fluid that drains from the nose can be collected and tested to see if it contains beta-2 transferrin, a protein unique to CSF.

How Common Are Csf Leaksand How Do They Occur

A spontaneous CSF leak is most common in women of childbearing age, Dr. Patel said, but it can also happen to men and at any age. Overweight individuals are also at increased risk since they tend to have higher blood pressure. Additionally, healthcare providers have noted an increase in CSF leaks due to rising rates of obesitya connection supported by an October 2017 Laryngoscope Investigative Otolaryngology study.

Research has suggested that spontaneous CSF leaks affect at least five out of every 100,000 people each year, and experts believe that many more people may go undiagnosed or misdiagnosed for long periods of time.

That number doesn’t include CSF leaks that are caused by trauma. CSF leaks can occur after a head, brain, or spinal surgery, a spinal tap, or any type of injury to the head, per MedlinePlus. Jackson stated that her runny nose, coughing, and sneezing began “a couple years after a traumatic car accident” in which her face hit the dashboard.

What Causes Cerebrospinal Fluid Leaks

A CSF leak results from several different causes. Some patients have unexplained elevated intracranial pressure which over time causes the bone between the brain and sinuses to remodel and become thinner ultimately leading to a CSF leak. Other patients get a CSF leak from hitting their head or face during a traumatic accident which causes a fracture of the thin bone separating the brain from the sinuses. In rare cases, patients getting sinus surgery can suffer a CSF leak if an inexperienced surgeon has accidentally penetrated through the thin sinus bones while operating.

People with certain conditions, including hypertension, Ehlers-Danlos syndrome and Marfan syndrome, are at greater risk for a CSF leak and women typically experience CSF leaks more often than men.2

Etiology Of Nasal Congestion And Rhinorrhea

Patients who use topical decongestants for > 3 to 5 days often experience significant rebound congestion when the effects of the drug wear off, causing them to continue using the decongestant in a vicious circle of persistent, worsening congestion. This situation may persist for some time and may be misinterpreted as a continuation of the original problem rather than a consequence of treatment.

Also Known As Csf Rhinorrhea

Everyone has experienced a runny nose at some point. Most often, a runny nose is caused by allergies, the common cold, or cold weather.

Very rarely, however, a runny nose can be caused by a condition called cerebrospinal fluid rhinorrhea, which is when the fluid that surrounds the brain leaks into the nose. CSF rhinorrhea can be caused by an injury or a surgical complication.

This article explains the causes, symptoms, and treatment of CSF rhinorrhea, and how you can tell the difference between a common runny nose and a CSF leak.

When A Runny Nose Is Brain Fluid Leaking: Here Is What To Do

Most cases of runny noses are not from central spinal fluid leaks.


It’s not snot. It’s leaking brain fluid.

That’s what Greg Phillpotts learned after suffering from a runny nose for 5 years, as described by Josh Chapin for ABC 11 Eyewitness News. Here’s a Tweet from Chapin:

He thought it was just allergies or even just a runny nose. It turned out to be something he needed surgery for. Its all next at 11 #ABC11@MountSinaiNYC

Josh Chapin

It turned out that Phillpotts was not experiencing constant allergies as he had been told previously. Instead, cerebral spinal fluid was leaking out into his nose. CSF is a fluid that surrounds your brain and spinal cord, cushioning, protecting, and supporting those parts of the body. CSF is one of the reason your brain doesn’t land with a thud every time you do a jumping jack or listen to Metallica. Normally, the membranes keep the CSF contained, a bit like a big water balloon around your brain and spinal cord. However, anything that may damage the membranes, such as a head injury, surgery, or a tumor, may leave a hole though which the fluid can leak out, potentially into your nose or ear.

Here’s a TODAY show segment about another person who had a somewhat similar experience:

If conservative approaches don’t resolve the leakage, surgery may be in order. Depending on where the defect is located, your doctor may be able to fix it with using a scope.

Woman’s Runny Nose Actually A Brain Fluid Leak

May 9, 2018 — A Nebraska woman who sought care for chronic allergies actually had a rare condition that allowed brain fluid to leak into her nose and mouth.

Kendra Jackson, 52, of Omaha, had coughing, sneezing, a chronic runny nose, and migraine headaches for nearly 2½ years. The symptoms started after she had a serious head injury in a car accident. Her doctors told her the symptoms were probably allergies or a bad cold.

“When it didn’t go away, I kept going back and forth to the doctors, and they prescribed every kind of medicine you can think of, and my nose just kept on running,” she told CNN.

This year, Jackson sought the care of doctors at Nebraska Medicine, who quickly realized her symptoms were likely due to something more serious. A CT scan revealed she had a rare condition — a cerebrospinal fluid leak — caused by a tiny hole in the thin bone that separates her brain and nasal cavities.

Christie Barnes, MD, a rhinologist at Nebraska Medicine who treated Jackson, says she knew just after examining her that a CSF leak probably was causing her to lose about a half-liter of fluid every day.

âHer description of the drainage that she had — itâs not typical for allergies,â Barnes says. âShe would wake up in the morning and the front of her shirt was saturated with fluid. And she would have a gush of fluid — tablespoons of fluid — from her nose. So it was not just a nuisance drip that youâd get from allergies.â

What Are The Symptoms Of A Csf Leak

CSF Leak Surgery – Nebraska Medicine

When CSF leaks are small enough that they dont noticeably affect your brain, you may not notice any symptoms or might mistake the symptoms for something else. When a CSF leak is large enough that it causes intracranial hypotension, youll have symptoms related to pressure on the lower areas of your brain.

The most common symptom of intracranial hypotension from a CSF leak is a postural headache, which means a headache that changes depending on your posture. A postural headache with a CSF leak worsens when you sit up or stand and improves when you lie down.

Symptoms that depend on CSF leak location

Some possible symptoms of CSF leak depend on the location of the leak. Two likely places that CSF can leak into are your sinuses or your nose. In either case, youll have a runny nose with thin, clear fluid. CSF coming out of your nose has two key differences from nasal mucus:

  • If you wipe your nose with a handkerchief, drying nasal mucus will cause the cloth to stiffen, but CSF wont.
  • The runny nose may happen under certain circumstances, such as when you bend over to pick something up or tie your shoes.

Another place where leaking CSF can cause symptoms is your ears. Clear fluid coming out of your ears is a symptom of a CSF leak. However, it’s less likely to happen because for the fluid to leak out, you’d also have to have a hole or tear in your tympanic membrane .

A positional headache is a leading symptom but depending on size can improve over time with long-term leakers. Often though, neurological symptoms increase. You can also have an increase in runny nose due to brain sag and irritation of the sinuses.

How Is A Csf Leak Treated

Dr. Kuperan will use diagnostic tools, such as a CT scan of your sinuses and nasal endoscopy to assess your condition in order to create a treatment plan. The nasal endoscopy can show where specifically the leak is coming from and the CT scan can visualize any fractures of the bone between the brain and the sinuses.

If there is a small leak a lumbar spinal drain can be placed to decrease the intracranial pressure. In this case, Dr. Kuperan would monitor you to see if the CSF leak spontaneously resolves.

A CSF leak that is severe or does not resolve after lumbar drain placement may require surgery to correct. Since the fluid leaking is clear it may be difficult to differentiate from ordinary mucus produced in the nose. In these cases, a dye called fluorescein can be injected into the CSF space through a lumbar spinal drain that turns the clear fluid into a yellow/green color. This technique localizes the CSF leak very efficiently. Once the source of the CSF leak is identified, the defect can be closed by performing a very technically specialized procedure called a cerebrospinal fluid leak repair.

What Can I Expect If I Have This Condition

CSF leaks are sometimes tricky to diagnose, but the overall outlook for this condition is good. While the symptoms can be unpleasant, severe or disruptive, this condition is usually treatable. The overwhelming majority of people who have CSF leaks will either recover when the leak heals or with treatments or surgeries.

How long does a CSF leak last?

CSF leaks can last days, weeks or even months, depending on the size of the leak and why it happened. Treatment can also greatly shorten how long you feel the effects of a CSF leak. Your healthcare provider is the best person to tell you more about how long this condition will affect you and what you can do to help yourself.

Whats the outlook for this condition?

Overall, the outlook for CSF leaks is very good. About 98% of people with CSF leaks will recover from them, no matter the cause.

Runny Nose Or Brain Fluid Leak

“Rhinorrhea” means “runny nose.” But a runny nose with brain fluid in it is different than allergies or a cold. If you’re leaking brain fluid, you’ll notice:

  • The fluid from your nose is watery and clear
  • Dripping in your throat
  • Drips increase when you put your head upside down
  • A salty or metallic taste in your mouth
  • Nasal congestion
  • Ringing in your ears

Having these symptoms doesn’t mean you have CSF rhinorrhea. You’ll need a diagnosis from an ENT specialist. They’ll test the fluid. Then they can use CT scans to locate the leak.

What Is A Csf Leak

Treatment of CSF leak – The Runny Nose & the Neurosurgeon – Part 4

A CSF leak happens when there’s a small tear in the durathe lining of the spinal cord and brain. When the fluid leaks out, the volume and pressure of fluid in your skull drops, leading your brain to slump.

“This ‘brain sag’ can trigger severe, relentless headaches, and can also cause vision and hearing disturbances, seizures and other symptoms such as neck pain and a heightened sense of smell,” explains Wouter I. Schievink, MD, director of Microvascular Neurosurgery and the Cerebrospinal Fluid Leak Program at Cedars-Sinai. “In other cases, cerebrospinal fluid can start draining from the nose, which is why many patients think they have a cold or allergy,” he adds.

A leak that occurs at the cranial level, rather than the spine, doesn’t result in the same drop in volume and pressure of fluid in the skull. A cranial CSF leak results in a runny nose and carries a high risk of meningitis, an inflammation of the membrane around the brain and spinal cord, which can be fatal and requires emergency attention.

What Causes A Csf Leak

Experts estimate that about 90% of CSF leaks happen because of injuries. The remaining 10% happen spontaneously or for unknown reasons.

Many injuries can cause CSF leaks. These include:

  • Injuries to your face, head, neck or spine. A common example of this is injuries from car crashes. The most likely injuries involve your nose, sinuses, ears, temples or the base of your skull. Twisting or severe whiplash can also cause tears that leak CSF fluid near your spinal cord.
  • Penetrating injuries .
  • Injuries from brain surgery.
  • Injuries from ear, nose and throat medical procedures.
  • Injuries from medical procedures on or around your spine, such as epidural anesthesia and spinal taps .

Non-injury causes

In about 10% of cases, CSF leaks happen for unknown reasons. However, experts have connected this problem to a few other medical conditions. Whether or not they cause CSF leaks is not yet known, but they do happen often enough that researchers are now looking to see if there is a cause-effect relationship.

  • Connective tissue disorders that could cause a weakness in the layers of tissue that should contain the CSF .
  • Structural defects in how your nose, sinuses or other parts of your skull formed .
