After ingestion of A cantonensis larvae, which are found in raw or undercooked mollusks, most patients with symptomatic disease present with nonspecific and self-limited abdominal pain caused by larval migration into the bowel wall. On rare occasions, the larvae can migrate into the CNS and cause eosinophilic meningitis. Although A cantonensis is prevalent in Southeast Asia and tropical Pacific islands, infestations from this parasitic nematode have been reported in the United States and the Caribbean. [21]
