aseptic meningitis (redirected from Meningitis, aseptic)

aseptic meningitis,

an inflammation of the meninges that is caused by one of a number of viruses, including coxsackie viruses and echoviruses (which account for about half the cases), nonparalytic polioviruses, and mumps, or may be drug induced, such as with high-dose IV immunoglobulin. Viral meningitis is especially common in children during the late summer and early fall. In about one third of the cases no pathogen can be demonstrated, but analysis of cerebrospinal fluid reveals increased numbers of white blood cells, usually lymphocytes; normal glucose concentration; slightly elevated protein levels; and no bacteria. Symptoms vary, depending on the causative agent and may include fever, headache, stiff neck and back, nausea, and skin rash. No specific treatment is available. Supportive therapy is directed to maintaining hydration and controlling fever. Complete recovery, without complication or residual effect, is usual. See also viral meningitis.
