Eosinophilic meningitis due to Angiostrongylus cantonensis in a Belgian traveller

Abstract

Eosinophilic meningitis is a rare clinical entity. The most frequent cause in travellers to the tropics is infection with the rat lungworm Angiostrongylus cantonensis. In this report, we describe a case of eosinophilic meningitis due to infection with this nematode in a traveller who presented with slight headache, diarrhoea, general malaise and thoracic radicular pain after a trip through Latin America and the Fiji Islands. She responded less than optimally to repeated steroid and albendazole treatments, but finally recovered completely.
