What happens if you leak too much CSF?

What happens if you leak too much CSF?

The tear or hole allows the CSF to leak out. The loss of CSF causes the previously cushioned brain to sag inside the skull, which results in a headache. Loss of fluid also causes a lowering of pressure within the skull, a condition called intracranial hypotension.

What is abnormal CSF?

Increased CSF pressure may be seen with a variety of conditions that increase pressure within the brain or skull and/or obstruct the flow of CSF, such as tumors, infection, abnormal accumulation of CSF within the brain (hydrocephalus), or bleeding.

What causes Xanthochromic CSF?

Xanthochromia is a yellow, orange, or pink discoloration of the CSF, most often caused by the lysis of RBCs resulting in hemoglobin breakdown to oxyhemoglobin, methemoglobin, and bilirubin. Discoloration begins after RBCs have been in spinal fluid for about two hours, and remains for two to four weeks.

What conditions can a lumbar puncture diagnose?

A lumbar puncture can help diagnose serious infections, such as meningitis; other disorders of the central nervous system, such as Guillain-Barre syndrome and multiple sclerosis; or cancers of the brain or spinal cord.

How often is CSF produced in the cerebrospinal fluid?

Cerebrospinal fluid is constantly produced at a secretion rate of 0.2-0.7 ml/min, meaning that there is 600–700 ml of newly produced CSF per day. Since the total volume of CSF averages around 150-270 mL, this means that the entire volume of CSF is replaced around 4 times per day. The pathway of the cerebrospinal fluid is as follows:

Where does CSF leak in the human body?

The fluid is contained by the meninges, a series of protective membranes that surround the brain and spinal cord. CSF leaks can cause fluid to leak through the ears, through the nose or into the spinal canal.

Can a lumbar drain be used for a CSF leak?

If hydrocephalus is suspected to be the cause of the CSF leak, a lumbar drain may also be placed in the lower back to decrease intracranial pressure.

How does a cisternogram test for CSF leak?

A cisternogram involves injecting a radioactive medium into the spinal fluid through a spinal tap and then performing CT scans. This test may help identify the origin of the CSF leak in the tissues adjacent to the spine or into the nasal cavities.
