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. [1]
[5] [92] [94] Symonds also described the use of lumbar puncture and xanthochromia in diagnosis. [95] The first surgical intervention was performed by Norman Dott, who was a pupil of Harvey Cushing then working in Edinburgh. He introduced the wrapping of aneurysms in the 1930s, and was an early pioneer in the use of angiograms. [5]
However, patients with confirmed CSF leaks may also demonstrate completely normal opening pressures. In 18–46% of cases, the CSF pressure is measured within the normal range. [24] [73] [74] [75] Analysis of spinal fluid may demonstrate lymphocytic pleocytosis and elevated protein content or xanthochromia. This is hypothesized to be due to ...
Though exact concentrations differ based on the specific disease, mild cases of lymphocytic pleocytosis are considered to begin when lymphocyte counts enter the range of 10-100 cells per mm 3. [1] In healthy individuals, only 0-5 white blood cells per μL are normally present in the CSF. [ 2 ]
In addition, damage to small blood vessels during lumbar puncture (traumatic tap) can lead to an increased CSF glucose since the blood that enters the collected CSF sample contains higher levels of glucose. [4] CSF glucose levels do not generally exceed 16.7 mmol/L (300 mg/dL). [3]
