What causes Xanthochromia in CSF?

Last Updated: 7th May, 2020

Xanthochromia is usually caused by red blood cell degeneration in the CSF as would be seen in subarachnoid hemorrhage (SAH). The breakdown of red blood cells takes many hours to occur. Other causes of xanthochromia include systemic jaundice and conditions causing elevated CSF protein.

Subsequently, one may also ask, what is Xanthochromia in CSF?

Xanthochromia. Xanthochromia, from the Greek xanthos (ξανθός) "yellow" and chroma (χρώμα) "colour", is the yellowish appearance of cerebrospinal fluid that occurs several hours after bleeding into the subarachnoid space caused by certain medical conditions, most commonly subarachnoid hemorrhage.

Subsequently, question is, how long does Xanthochromia CSF last? All patients had xanthochromia of the CSF. Lumbar punctures were performed between 12 hours and one week after the ictus. Xanthochromia was still present in all (41) patients after 1 week, in all (32) patients after 2 weeks, in 20 of 22 patients after three weeks and in 10 of 14 patients after four weeks.

Similarly, it is asked, what causes blood in CSF?

Xanthochromia is most often caused by the presence of blood, but several other conditions should be considered. Red blood cells in CSF caused by a traumatic tap or a subarachnoid hemorrhage artificially increase the white blood cell count and protein level, thereby confounding the diagnosis.

What causes increased protein in CSF?

An abnormal protein level in the CSF suggests a problem in the central nervous system. Increased protein level may be a sign of a tumor, bleeding, nerve inflammation, or injury. A blockage in the flow of spinal fluid can cause the rapid buildup of protein in the lower spinal area.

How long does it take for Xanthochromia to develop?

Therefore, xanthochromic CSF at the time of LP indicates SAH; however, xanthochromia can take as long as 12 hours to develop (19), and delaying an LP for that long after ictus to ensure its appearance may be unacceptable.

What color is CSF fluid?

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.

What does yellow CSF fluid mean?

A yellowish tinge to the CSF fluid is called xanthochromia. Xanthochromia is usually caused by red blood cell degeneration in the CSF as would be seen in subarachnoid hemorrhage (SAH). The breakdown of red blood cells takes many hours to occur.

How do you read CSF results?

The CSF is cloudy on inspection, the white cell count is significantly raised and glucose levels are low. The history and CSF results are strongly suggestive of bacterial meningitis and therefore he should be treated empirically whilst culture results are awaited.

Are lymphocytes normal in CSF?

Lymphocytic pleocytosis is an abnormal increase in the amount of lymphocytes in the cerebrospinal fluid (CSF). Under normal conditions, there are usually less than 5 white blood cells per µL of CSF. In a pleocytic setting, the number of lymphocytes can jump to more than 1,000 cells per µL.

Does CSF contain blood?

CSF cell count. Normally, there are no RBCs in the cerebrospinal fluid, and there should be no more than five WBCs per cubic millimeter of CSF. If your fluid contains RBCs, this may indicate bleeding. It is also possible that you had a traumatic tap (blood leaked into the fluid sample during collection).

What does high CSF RBC mean?

Finding red blood cells in the CSF may be a sign of bleeding. However, red blood cells in the CSF may also be due to the spinal tap needle hitting a blood vessel. Additional conditions which this test may help diagnose include: Arteriovenous malformation (cerebral) Cerebral aneurysm.

What is a traumatic LP?

The lumbar puncture (LP) is a common Emergency Department (ED) procedure often used in the diagnosis of subarachnoid hemorrhage (SAH). Although the LP is a relatively simple test, significant diagnostic uncertainty can arise when trauma from the needle causes bleeding into the subarachnoid space.

What does blood in CSF indicate?

The presence of red blood cells may indicate bleeding into the CSF or may indicate a "traumatic tap" - blood that leaked into the CSF sample during collection. A significant increase in white blood cells in the CSF is seen with infection or inflammation of the central nervous system.

What does CSF look like in bacterial meningitis?

Bacterial meningitis is diagnosed by CSF examination. Typical findings are: elevated opening pressure, elevated protein and hypoglycorrhachia. The fluid appearance may be cloudy or turbid. The CSF leukocyte concentration is usually elevated with a neutrophilic pleocytosis.

What diseases can be found in spinal fluid?

Infectious diseases of the brain and spinal cord, including meningitis and encephalitis. CSF tests for infections look at white blood cells, bacteria, and other substances in the cerebrospinal fluid. Autoimmune disorders, such as Guillain-Barré Syndrome and multiple sclerosis (MS).

What Color Is Spinal fluid with meningitis?

Turbid (cloudy) CSF can reflect infection within the CSF (meningitis). A red color occurs with new blood or brownish with old blood.

Rio Siemsen


Why is protein high in CSF in bacterial meningitis?

CSF protein
Bacterial meningitis leads to a more permeable blood brain barrier (due to increased inflammation). Protein leaks into the subarachnoid space from the blood, resulting in markedly increased CSF protein levels.

How do you correct RBC in CSF?

1 WBC : 500 (or 1,000) RBC
For every 500 (or 1,000) RBCs in the CSF, you can have 1 WBC in the CSF. You can simply subtract this “allowable” number of WBCs from the actual number in the CSF analysis. Now you have a “corrected” WBC count that you can interpret.

How much CSF is produced per hour?

In normal adults, the CSF volume is 125 to 150 mL; approximately 20 percent of the CSF is contained in the ventricles; the rest is contained in the subarachnoid space in the cranium and spinal cord. The normal rate of CSF production is approximately 20 mL per hour.

What is CSF in meningitis?

Spinal tap (lumbar puncture).
For a definitive diagnosis of meningitis, you'll need a spinal tap to collect cerebrospinal fluid (CSF). In people with meningitis, the CSF often shows a low sugar (glucose) level along with an increased white blood cell count and increased protein.

Can you die from spinal fluid leak?

OJAI, CA—Spontaneous CSF leaks are treatable, often misdiagnosed, and can cause a neurologic syndrome that may include headache, nausea, and tinnitus. Spinal fluid leaks also can lead to serious complications, including seizures. Patients may have a CSF leak for years or decades before it is diagnosed.

Can CSF be yellow?

Elevated CSF protein levels may cause yellowish discoloration of the CSF because of the presence of albumin-bound bilirubin; this usually requires a protein concentration in excess of 150 mg/dl.

How long is LP positive after SAH?

An LP is performed to evaluate the cerebrospinal fluid for the presence of red blood cells (RBCs) and xanthochromia. LP may be negative if performed less than 2 hours after an SAH occurs; LP is most sensitive 12 hours after onset of symptoms.
