Lymphocytic pleocytosis

Lymphocytic pleocytosis is an abnormal increase in the amount of lymphocytes in the cerebrospinal fluid (CSF). It is usually considered to be a sign of infection or inflammation within the nervous system, and is encountered in a number of neurological diseases, such as pseudomigraine, Susac's syndrome, and encephalitis. While lymphocytes make up roughly a quarter of all white blood cells (WBC) in the body, they are generally rare in the 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 mm3. Increases in lymphocyte count are often accompanied by an increase in cerebrospinal protein concentrations in addition to pleocytosis of other types of white blood cells.
==History==
Determination of lymphocytic pleocytosis became possible with the advent of the diagnostic lumbar puncture and the technology necessary to analyze the cerebrospinal fluid via microbiological, biochemical, and immunological tests. While the first lumbar punctures were performed in the late 19th century, the tests revealing elevated lymphocyte levels within the CSF were not available until much later. Modern lumbar punctures testing for lymphocyte counts are commonly used to diagnose or rule out certain diseases such as meningitis and determine whether an infection is present within the CSF.
