Eosinophilic meningitis--a case report and literature review.

A case of eosinophilic meningitis in a young boy from Indonesia is reported. Clinically, he had a subacute meningitis with eosinophilic pleocytosis in the cerebrospinal fluid. The clinical and laboratory findings strongly suggest Angiostrongylus cantonensis as the aetiologic agent although the parasite was not found. The other most likely causes in the region are also considered and the life-cycle of Angiostrongylus cantonensis and the epidemiology of its infection are briefly reviewed.
