[Eosinophilic meningitis (author's transl)]

Eosinophilic meningitis, also named human nervous angiostrongyliasis, results from the infestation of the Nervous System by larvae of Angyostrongylus Cantonensis realizing there a parasitic deadlock. The Authors studied 54 patients whose main complaints were severe and lasting headache, and paresthesias. A meningitic syndrome is not always encountered and a facial paralysis of the lower motor neuron type has been noted in a few patients. Study of the Cerebrospinal fluid shows pleiocytosis with a variable percentage of eosinophiles. Complete recovery is usual after a couple of weeks and the prognosis can be given as excellent despite of the fact that no specific therapy is known at the present time.
