[1st case of eosinophilic meningitis in Reunion, probably due to Angiostrongylus].

Report of the case of a six-year-old child who presented a meningitis with 40 % eosinophils in the cerebrospinal fluid and which spontaneously regressed. These clinical data and the serologic (positive test for many nematod antigens) and epidemiological findings (presence of Angiostrongylus larvae in terrestrial gasteropod) lead to the conclusion that we were in presence of the first case of eosinophil meningitis due to Angiostrongylus cantonensis reported in the island of la Réunion.
