ABSTRACT
Meningoencephalitis is an acute inflammation of the brain and spinal cord and their covering protective membranes. Meningitis can be life-threatening because of the inflammation's proximity to the brain and spinal cord; therefore, the condition is classified as a medical emergency
The commonest symptoms of meningitis are headache and neck stiffness associated with fever, confusion or altered consciousness, vomiting, and an inability to tolerate light [photophobia] or loud noises [phonophobia]. Children often exhibit only nonspecific symptoms, such as irritability and drowsiness. If a rash is present, it may indicate a particular cause of meningitis; for instance, meningitis caused by meningococcal bacteria may be accompanied by a characteristic rash
A broad variety of allergic, infectious, neoplastic, and idiopathic diseases are associated with increased blood and/or tissue eosinophilia and range in severity from self-limited conditions to life-threatening disorders. Although accepted upper limits of normal blood eosinophil numbers vary somewhat, a value above 600 eosinophils /microL of blood is abnormal in the vast majority of cases. Generally speaking, there are several possible causes of eosinophils in the CSF; undoubtedly parasitic infection is one of the main causes
