Cerebrospinal fluid analysis showed a moderate pleocytosis with lymphocyte predominance and elevated proteins, oligoclonal bands profile 3, elevated immunoglobulin G (IgG) index, and negative microbiological testing including tuberculosis and West Nile polymerase chain reaction (PCR); the cytofluorimetric analysis of the lymphocytes revealed a T-cell predominance (65%) with elevated CD4/CD8 ratio (CD4 85%/CD8 15%) in absence of monoclonality. Here, CD8A is linked to tuberculosis.
