Angiostrongylus cantonensis
Angiostrongylus cantonensis is the most common cause of eosinophilic menhingitis in asia and the south pacific - but you havent told us the where the patient had been previous to becoming ill, i wouldnt like to say for sure that it is this. The stained sections definatly show nematodes however and I can't think of any other brain enchephalitis causing nematodes right now...
I'll go with Angiostrongylus cantonensis as well. Perhaps the patient does have history of travel that we just don't know about - after all, sometimes the whole picture
...isn't presented by those submitting specimens, etc.
A. cantonensis "has also been found in Australia, some areas of Africa, the Caribbean, Hawaii and Louisiana."
