Characteristic Of Mumps And Lymphocytic Choriomeningitis between 500 and 1000 cells are also characteristic of mumps and lymphocytic choriomeningitis. Simulation of train Abscess or Bacterial Meningitis. Confusion with meningococcal and other bacterial meningitis may also arise in echo9 or other enterovirus infections with a petechial rash. If reasonable doubt exists, however, the case should be treated as one of purulent meningitis until this has been excluded by appropriate cultures. Inadequately treated bacterial meningitis and mechanical irritation of the meninges owing to brain abscess (or other intracranial lesions) may also produce an aseptic meningitis syndrome.
The possibility of a silent brain abscess is suggested by a history of recent pneumonia, chronic pulmonary infection, congenital heart disease, bacterial endocarditis, otitis media, or infection of the paranasal sinuses. Other Forms of Aseptic Meningitis. Leptospirosis is to be considered seriously in areas where the infection is common and when there is a history of exposure to dogs, cattle, swine, or rats, which excrete the agent in their urine.
The presence of respiratory symptoms and central nervous system signs suggests the possibility of infection with this agent; a significant titer of cold agglutinins in the serum supports the diagnosis. Treatment. Bed rest, adequate fluid intake, and symptomatic treatment are indicated, as in any acute febrile illness. Prognosis. Aseptic meningitis caused by viruses is a self-limited disease, complete recovery occurring in three to five days in mild cases, and in seven to fourteen days in the more severe ones.
