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.
This syndrome is called aseptic meningitis, because no bacterial organisms are isolated. The most common agents causing aseptic meningitis are enteroviruses. Involvement of neurons and glial cells by viruses (viral encephalitis) impairs neurological function and causes seizures, focal neurologic deficits, and coma. Encephalitis is accompanied by viral meningitis whereas aseptic meningitis may occur alone.
