Case ReportsFour documented cases of eosinophilic meningoencephalitis due to Angiostrongylus cantonensis in Hong Kong.
4 cases of eosinophilic meningoencephalitis in Hong Kong are described. The major clinical features of the patients, who were 2-60 years old, were low grade fever, headache, mild meningeal signs, right facial palsy or hemiplegia. Eosinophilia in the peripheral blood and eosinophilic pleocytosis were prominent. ⋯ Sections of a nematode observed in the brain of a patient who died were identified as those of young adult Angiostrongylus cantonensis. High ELISA titres against the crude antigens of this nematode were also noted in the serum of 3 patients. The disease is probably under-recognized in Hong Kong.
