Meningitis is characterized by inflammation of the leptomeninges.Meningitis causes are divided to infectious and non-infectious process.Infectious causes are included,bacterial,viral,fungal,protozoal and,treponemal. non-infectious causes, such as systemic illnesses that may involve CNS (e.g. neoplasms or connective tissue diseases, such as sarcoidosis, systemic lupus erythematosus (SLE), and wegener's) or certain drugs (e.g. nonsteroidal antiinflammatory drugs, intravenous immunoglobulin, intrathecal agents, and trimethoprim-sulfamethoxazole).
