If a patient suffers from a runny nose that doesn’t improve and a headache that only occurs when they are upright, they might be suffering from a CSF leak. This condition is usually the result of an accident or a tumor, but it can also appear spontaneously. Sinus specialists take cerebrospinal leaks very seriously because they can lead to serious complications and even death. Let’s examine this problem in more detail.

What Is a CSF Leak, and What Are the Symptoms? 

Cerebrospinal fluid is vital for brain function, and it is mainly produced in an area of the brain called the choroid plexus. The fluid is made up of amino acids, glucose, water, and electrolytes, and it doesn’t normally contain cells. A cerebrospinal fluid leak occurs when the lining of the brain is damaged and the fluid that usually flows around and protects the brain comes out of the nose.

 

The average human produces 500 mL of cerebrospinal fluid per day; however, a leak can develop into meningitis, an inflammation of the membrane that surrounds the brain and spinal cord. It is vital that patients seek medical attention immediately if they experience persistent nasal dripping, headaches, hearing problems, imbalance, excessive sensitivity to light, or stiff neck.

 

Causes of a Cerebrospinal Fluid Leak

Around five out of 100,000 people develop a cerebrospinal fluid leak each year, so the condition is relatively common. Despite this, not every doctor can correctly diagnose this issue, especially because some of the symptoms mimic those of a migraine. If a patient suffers from the symptoms associated with a cerebrospinal fluid leak, they should speak to a sinus specialist with a proven track record.

 

This doctor can let them know whether it’s likely that they have this condition. However, it can also occur spontaneously in a patient who didn’t have any symptoms before they developed the leak.

 

An Accident 

The vast majority of cerebrospinal leaks are caused by trauma to the head. This could happen during an accident, but it also sometimes occurs when a brain or sinus surgery goes wrong. Often, patients notice the problem right away, but a cerebrospinal fluid leak can still present itself many weeks or months after the trauma. In the three months after an accident, patients should be careful and watch out for the above-named symptoms.  

 

A Tumor 

Benign brain tumors don’t usually cause a leak, but a cancerous growth could lead to this condition because it wears away the bone at the base of the skull. Fortunately, the cerebrospinal leak can usually be repaired during the same surgery that removes the patient’s tumor.

 

No Cause 

Most of the time, brain fluid doesn’t leak unless there is a clear cause. But occasionally, patients without a tumor or trauma experience this problem. Usually, they have an underlying condition such as bone spurs or calcified disc material.

 

The reason for a spontaneous leak is thought to be high intracranial pressure or a buildup of pressure in the brain and study revealed that high ICP can be caused by a blood clot, infection, an abnormally shaped blood vessel, and occasionally a blockage in the circulation of fluid at the bottom of the patient’s brain. As ICP builds, it places pressure on the skull, which wears away the bone. Eventually, a hole forms and a cerebrospinal leak develops.

 

Does a Sinus Infection Cause a Cerebrospinal Fluid Leak?

One of patients’ most frequently asked questions is can a sinus infection cause a CSF leak? The answer is that it is unlikely. However, cerebrospinal leaks are often confused with sinusitis. If patients’ symptoms don’t improve within a few days or weeks, it’s wise to run further tests and check for a brain fluid leak.

 

What to Do When You Suspect a Cerebrospinal Fluid Leak 

Cerebrospinal leaks are often misdiagnosed, so anyone experiencing symptoms must visit a specialist. At the clinic, the sinus doctor might run tests to check whether the patient is really suffering from a leak or whether they have another condition.

 

Fluorescein dye is sometimes applied to the spinal canal to determine whether fluid is leaking through the nose. A CT scan or an MRI may also be done. Once the doctor has confirmed that the patient suffers from a cerebrospinal fluid leak, they will treat them immediately and the patient may need an epidural blood patch, an epidural sealant, or transvenous embolization, but some patients can avoid surgery.

 

What Is the Prognosis? 

When treated early, patients with a cerebrospinal fluid leak can make a full recovery. This is true no matter the cause of the condition. However, those who develop the leak spontaneously might require several treatments or surgeries because they often have an underlying spinal or bone condition that causes the problem.

 

There is a serious problem when cerebrospinal fluid leaks, which could lead to meningitis if not treated right away. An accident, a wrongly performed surgery or a brain tumor may cause patients to experience this problem. Sometimes, it occurs spontaneously. A dye can be used to diagnose cerebrospinal leaks through imaging studies.
