With aseptic meningitis a person has signs and symptoms of meningitis, but bacteria does not grow in cultures. Many different things can cause aseptic meningitis including viruses, fungi, tuberculosis, some medications and infections near the brain or spinal cord, such as epidural abscesses.
Aseptic meningitis is similar to other forms of meningitis, but the cause is not a bacterial infection of the meninges or CSF. Aseptic meningitis can be caused by viruses, some drug reactions, and certain conditions, such as tuberculosis, brain surgery, head injury, cancer, or Lyme disease.
