Eosinophilic Meningitis in an Emergency Department: Report of 5 Cases

Meningitis is an emergent and often lethal disease seen in the emergency department. Eosinophilic meningitis is a relative rare condition of meningitis. Angiostrongylus cantonensis, the most common cause of eosinophilic meningitis, has spread from Southeast Asia to the South Pacific. In this article, I report 5 cases of eosinophilic meningitis, caused by Angiostrongylus cantonensis. Patients presented with severe headache, neck pain, nausea, and vomiting. According to their detailed histories, I suggest that uncooked vegetables, which may have been contaminated by snail, are the cause of this familial outbreak of eosinophilic meningitis. The patients were admitted for treatment and discharged without any neurological sequelae.
