What mimics a CSF leak?

POTS, orthostatic hypotension, cervicogenic headache, vestibular migraine, and prior Chiari decompression surgery are all causes of orthostatic headache that may mimic spinal CSF leak and must be distinguished for patients to receive appropriately directed therapy.

Can a CSF leak be misdiagnosed?

Dr. Carroll believes that cerebrospinal fluid leaks are often misdiagnosed, and more common than previously thought.

How do you rule a CSF leak?

CT myelography.

This test is considered the gold standard for diagnosing and locating CSF leaks. It uses a CT scan and a contrast dye to locate CSF leaks anywhere in the skull base. It provides the most precise location of a CSF leak and helps to determine the most appropriate treatment plan.

Can CSF leak symptoms come and go?

Patients who have had a CSF leak have described the fluid as having a salty or metallic taste. Dr. Frank P.K. Hsu, chair of the department of neurological surgery at UC Irvine Health, said that the fluid may also “come and go.”

How do I know if my drainage is CSF?

To determine the exact location of the leak, a CT cisternogram would be performed. A CT cisternogram involves using a contrast injected into the spinal fluid through a spinal tap and then performing CT scans. This test identifies the exact location of the CSF leak and the pathway of the drainage into the nose.

Cerebrospinal Fluid (CSF) Leak — What You Need to Know

How can you tell the difference between nasal discharge and CSF?

Identifying of CSF leakage

Handker chief test: When the discharge from the nose is buried in a handkerchief or dry gauze, the CSF is more likely to be clear if it is not sticky The Handker chief test is a test to determine the nasal discharge, which is unclear and sticky due to mucin secretion from the nose.

What color is a CSF leak?

The classic presentation of CSF leaks is the expression of clear, watery drainage from the nose. This occurs usually on one side; however if fluid drains into the back of the throat there may be a salty taste. Drainage also tends to increase when bending over or straining.

What does a spinal fluid leak feel like?

The most common symptoms of a spinal CSF leak are: Positional headaches, which feel worse when sitting upright and better when lying down; caused by intracranial hypotension. Nausea and vomiting. Neck pain or stiffness.

What does a CSF headache feel like?

The headache is generally worse shortly after sitting up or standing and improves relatively quickly when laying down, hence it is often referred to as an “orthostatic” or “postural” headache. The pain can range from mild to severe and can feel more like pressure than pain and be accompanied by a heaviness.

Can you see CSF leak on MRI?

Magnetic resonance imaging (MRI) accurately detects CSF leaks and associated complications such as the encephaloceles and meningoceles.

Does CSF show up in blood tests?

Changes in the elements of your CSF due to central nervous system diseases or other serious conditions are often first and most easily detected in a sample of your spinal fluid. Tests on blood and urine may be used in conjunction with CSF analysis to evaluate your condition.

How should I sleep with CSF leak?

How long does CSF leak last?

Most of posttraumatic CSF leakage resolves within six months after trauma. CSF fistula should be closely evaluated because of fatal complication.

Can CSF leak mimic POTS?

This case suggests that a CSF leak can cause secondary POTS. Therefore, POTS should be considered in patients with orthostatic headaches, even in the presence of a CSF leak.

Can you have intracranial hypotension without a leak?

Thus, in rare cases, intracranial hypotension may occur in the absence of CSF leakage from the dural sac. Conclusion: We propose a pathophysiological concept for the subgroup of SIH patients with typical cranial imaging findings and no evidence of CSF leakage.

What does CSF taste like?

An individual with a CSF leak may also notice clear, watery fluid draining from their nose or ears when they move their head, especially when bending forward. CSF may also drain down the back of the throat. People describe the taste as salty and metallic.

How common is a spontaneous CSF leak?

How common is a CSF leak? Spontaneous CSF leaks (ones that are not triggered by a medical procedure such as a lumbar puncture, or by a serious injury such as a gunshot wound) occur in at least five in 100,000 people per year, making them fairly rare.

Can you have CSF leak for years?

Patients may have a CSF leak for years or decades before it is diagnosed. “It is often mysterious where the leak is and what is causing it,” said Ian Carroll, MD, at the 10th Annual Winter Conference of the Headache Cooperative of the Pacific.

Can a spontaneous CSF leak heal on its own?

Most cases heal by themselves with no lasting symptoms. If the CSF leak keeps coming back, high pressure of the CSF (hydrocephalus) might be the cause and should be treated.

When should I go to the ER for CSF leak?

If a CSF leak is suspected, you should see a physician as soon as possible. If symptoms of meningitis (high fever, light sensitivity, neck stiffness) are suspected, you should go to the emergency room.

What are the symptoms of a dural tear?

If a defect goes undetected or is not properly closed, the patient is likely to experience a postural headache with a combination of the following symptoms: nausea, vomiting, pain or tightness in the neck or back, dizziness, diplopia due to VI cranial nerve paresis, photophobia, tinnitus, etc.

Does CSF leak cause stuffy nose?

When a leak occurs, your CSF pressure drops around the brain and spinal cord. This is a very serious condition that may lead to the following symptoms: Clear drainage from the nose or into the back of the throat. Nasal congestion that does not improve with medications for a runny nose.

Is CSF yellow or clear?

Color of the fluid—normal is clear and colorless. Changes in the color of the CSF are not diagnostic but may point to additional substances in the fluid. Yellow, orange, or pink CSF may indicate the breakdown of blood cells due to bleeding into the CSF or the presence of bilirubin.

Can CSF leak cause coughing?

If a patient with CSF leak after ESS experiences fever, cough, or fatigue, physicians should consider aspiration pneumonia in addition to meningitis.

How do you test for CSF leak in nose?

Testing fluid from the ear or nose for β-2 transferrin is the recommended method to assess patients for a cranial CSF leak because this approach is noninvasive as well as highly sensitive and specific. Immunofixation electrophoresis is the method typically used.
