[A case of primary acute eosinophilic meningitis]

The authors present a case of meningitis with a significant eosinophilic pleiocytosis in the cerebrospinal fluid in a eighteen months old girl. The rapidly favourable course and the negative parasitological research direct the diagnosis to acute primary eosinophilic meningitis. The meaning of the presence of some colonies of H. influenzae in the cerebrospinal fluid is discussed.
