Background: Angiostrongylus cantonensis is the etiological agent of neuroangiostrongyliasis in humans, which is developed in gastropods and vertebrate species, mainly rodents. Human transmission occurs through consumption of molluscs and paratenic hosts infected with L3, and the migration of larvae to the central nervous system causes eosinophilic meningitis. Laboratory diagnosis is based on molecular and immunological tests, using young or adult females as a source of antigens.

Gastropod molluscs are used as intermediate hosts and rats of various species are definitive hosts of this parasite. In this study, we identified several environmental factors associated with the presence and abundance of terrestrial gastropods in an impoverished urban region in Brazil.

- A rat lungworm, a major cause of eosinophilic meningitis in humans, is contracted through eating infected intermediate hosts or contaminated produce, mainly in tropical and subtropical areas.
- Human cases of angiostrongyliasis have been noted in Brazil since 2007, particularly in the Southeast, Northeast, and South regions.
- In a study conducted in São Paulo in 2011, researchers identified the parasite in rodents and confirmed its presence through various tests, marking the first report of natural infection in both intermediate and definitive hosts in this urban area of Brazil.
Introduction: Angiostrongylus cantonensis is a natural parasite found in lung arteries of rats, which in humans may cause eosinophilic meningitis.
Objective: To report the first case of eosinophilic meningitis caused by Angiostrongylus cantonensis in the city of São Paulo, Brazil.
Case Report: A male patient, 11 years old, living in the southern area of São Paulo, was admitted to the Pediatric Emergency Department with ongoing headaches for three days, but no fever or any other complaint.
