Elsberg syndrome with eosinophilic meningoencephalitis caused by Angiostrongylus cantonensis.

A 42-year-old man was admitted to our hospital with a history of fever, headache and disorientation. His cerebrospinal fluid revealed eosinophilia and his serum had an antibody against Angiostrongylus cantonensis (A. cantonensis). Then, he was diagnosed as eosinophilic meningoencephalitis caused by A. cantonensis. He was treated with repeated lumbar punctures and oral prednisolone. Although a symptom he had been suffering from at the time of his admission was urinary retention, this symptom disappeared as his general condition improved. Therefore his case was considered to be Elsberg syndrome with eosinophilic meningoencephalitis caused by A. cantonensis.
