Can a CSF leak go unnoticed?

CSF leaks are often unrecognized and untreated for long periods of times. The most common symptom of delayed diagnosis is simply clear runny discharge associated with positional headaches (headaches that get worse when standing up, or change in quality when laying down).

Can you have a CSF leak for years and not know it?

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.

How fast is a CSF leak?

CSF fistula occurs in 2-3% among patients with head injury, 60% of CSF fistula occurs within days of trauma, and 95% within 3 months

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.

Does CSF leak always show on MRI?

Spinal CSF leaks can exist without any evidence of a leak on imaging. A negative MRI of the brain or spine does not rule out a spinal CSF leak. Even when positive for a CSF leak, current spinal imaging is not always adequate for locating all leaks. Symptoms are usually key in diagnosing a leak, as noted above.

Can a CSF leak cause neurological problems?

When this fluid volume is reduced, there is less fluid available to cushion the brain inside the skull. This loss of CSF causes headache and other neurological signs and symptoms and may result in a range of complications. With upright posture, the loss of CSF volume has a greater effect on the brain.

How long can CSF go untreated?

Prognosis for spontaneous spinal CSF leaks
Some patients with spontaneous leaks have symptoms that resolve spontaneously in a matter of hours, days, or weeks without ever seeking medical care. A substantial percentage of patients respond favorably to one or more epidural blood patching procedures.

What does high CSF pressure feel like?

Intracranial hypertension means that the pressure of the fluid that surrounds the brain (cerebrospinal fluid or CSF) is too high. Elevated CSF pressure can cause two problems, severe headache and visual loss. If the elevated CSF pressure remains untreated, permanent visual loss or blindness may result.

Can CSF leak be missed on MRI?

If MRI with this specific CSF leak protocol is not deployed, a subtle leak may be missed, and, even sometimes, with an accurately performed MRI, some of the leaks cannot be diagnosed.

Can you have a CSF leak and IIH?

In rare cases, spontaneous CSF leak can present as a manifestation of IIH. Several cases with spontaneous CSF leak have been reported with IIH. In some cases, patients have developed it in a known setting of IIH [8, 10].

Is CSF leak constant or intermittent?

In patients with spontaneous CSF leaks, the diagnosis may be more difficult to confirm because the leak may be small and intermittent drainage is common.

Can you have a CSF leak and high pressure?

Spontaneous CSF leaks are sometimes referred to as high-pressure leaks when increased ICP contributes to the development of the CSF leak (2,3). Idiopathic intracranial hypertension (IIH) is increasingly recognized as a cause of spontaneous CSF leak in the ENT and neurosurgical literature (2-8).

Can high blood pressure cause a CSF leak?

Non-injury causes
Connective tissue disorders that could cause a weakness in the layers of tissue that should contain the CSF (examples include Marfan syndrome and Ehlers-Danlos syndrome). Intracranial hypertension (high pressure inside your skull), which can cause tears in the surrounding tissue, creating a leak.

Can CSF leak show up in blood work?

Beta (β)-2 transferrin testing is the preferred laboratory approach to assess patients for cranial CSF leaks because it is highly specific and sensitive for CSF secretions. The β-2 transferrin in CSF is a desialylated form due to the presence of neuraminidase in the central nervous system.

What causes high pressure in CSF?

This can be caused by a mass (such as a tumor), bleeding into the brain or fluid around the brain, or swelling within the brain itself. An increase in intracranial pressure is a serious and life-threatening medical problem.

Do you feel sick with CSF leak?

Symptoms may include: A headache that is worse when you sit up and improves when you lie down. It may be associated with light sensitivity, nausea, and neck stiffness. Drainage of CSF from the ear (rarely).

When should you suspect a CSF leak?

The most common symptom of a spinal CSF leak is a headache, while a cranial CSF leak causes symptoms such as clear fluid leaking from the nose or ear. Some CSF leaks may heal with conservative treatments such as bed rest. Many CSF leaks need a blood patch to cover the hole or surgery to repair the leak.

How do I know if my nasal drainage is CSF?

How do I know if my CSF is leaking?

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 doctor can diagnose a CSF leak?

Our sinus specialists, otologists/neurotologists, and neurosurgeons collaborate to diagnose and treat cranial CSF leaks. These are most often treated with surgery.

What should I avoid with a CSF leak?

You will need to stay in bed with your head raised and avoid activities that cause pressure. These activities include coughing, vomiting, blowing your nose, and straining to have a bowel movement. Your provider may give you medicines to stop any coughing and vomiting.

How do you rule out a CSF leak?

Myelography. This test is considered the gold standard for diagnosing and locating CSF leaks. It uses digital subtraction fluoroscopy, a CT or MRI scan, and a contrast dye to locate CSF leaks. It provides the most precise location of a CSF leak and helps to determine the most appropriate treatment plan.

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

What can mimic 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.

What does a CSF headache feel like?

The classic symptom is a headache that becomes severe when the patient is upright and quickly disappears when the patient is lying flat. So, the headaches are typically absent first thing in the morning, and start or worsen shortly after getting out of bed.

Which is the most common site of CSF leak?

[1] The most common site for spontaneous CSF leak is the cribriform plate followed by the ethmoid roof. Primary CSF leaks can also involve the sphenoid sinus, peri sella, or pterygoid recesses.
