Quizplus · Accepted Answer

Aseptic meningitis is characterized by lymphocytic pleocytosis in the cerebrospinal fluid (CSF) without the identification of an organism on routine culture and Gram stain. This condition is usually caused by non-bacterial agents such as viruses or fungi. Purulent meningitis is characterized by the presence of pus in the CSF and is usually caused by bacteria such as Streptococcus pneumoniae or Neisseria meningitidis. Septic meningitis is a severe form of bacterial meningitis that is characterized by the rapid onset of symptoms and high mortality rate. Malignant meningitis is a rare but serious complication often seen in cancer patients where the tumor cells spread to the meninges of the brain and spinal cord.
