High lymphocytes in cerebrospinal fluid (CSF), a condition known as lymphocytic pleocytosis, indicates inflammation in the central nervous system (CNS).
In more detail:
- Lymphocytes and CSF: Lymphocytes are a type of white blood cell crucial for the immune system's response to infections and other inflammatory conditions. CSF is the fluid that surrounds the brain and spinal cord.
- Lymphocytic Pleocytosis: The term "lymphocytic pleocytosis" specifically refers to an elevated number of lymphocytes in the CSF. According to reference [35], it is "an indicator of inflammation in the CNS".
Therefore, finding high levels of lymphocytes in a CSF sample typically suggests that there is an inflammatory process occurring within the brain or spinal cord. The cause of this inflammation needs to be further investigated to determine the appropriate treatment.
