Plasma cell pleocytosis has been seen in cerebrospinal fluid (CSF) analysis of patients with multiple myeloma, multiple sclerosis, leukemia, west nile encephalitis and lymphoma. There also have been some anecdotal reports suggesting the presence of plasma cells in CSF as possible early indicator of WNV encephalitis. We describe a case of plasma cell pleocytosis in CSF due to HSV-2 meningitis, adding it to the list of possible etiologies for the same.
