In contrast to patients with bacterial meningitis, patients with aseptic meningitis syndrome usually appear clinically nontoxic, with no vascular instability. (See Aseptic Meningitis.) In many cases, a cause for meningitis is not apparent after initial evaluation, and the condition is therefore classified as aseptic meningitis. These patients characteristically have an acute onset of meningeal symptoms, fever, and CSF pleocytosis that is usually prominently lymphocytic.
