Abstract

Fever of unknown origin (FUO) in children is frequently caused by infectious diseases. Angiostrongylus cantonesis, while a primary cause of eosinophilic meningitis, is a rare cause of FUO. We report a 17-month-old patient admitted with FUO, no sign and symptom of meningococcal disease, but had elevated peripheral eosinophils count (32%). We performed lumbar puncture ​​to find the cause of FUO. The results was greater than 2000 leukocytes/μl (32% eosinophils), Elisa serum and CSF was positive with Angiostrongylus cantonesis . The patient was diagnosed with eosinophilic meningitis caused by Angiostrongylus cantonesis and responded well with treatment. Conclusion: In young children, symptoms of parasites infections may be atypical. In children with FUO and elevated peripheral blood eosinophils, the physicians need to carefully review the medical history and examine patients to identify parasites infection, with special focus on central nervous system infection.
