[Trichinosis of the central nervous system. One case (author's transl)].

A case of trichinosis involving the cental nervous system is presented. The neurological symptoms developed 20 days after ingestion of the larvae and 3 days after the onset of facial oedema. They consisted of behavioural disorders, tetraparesis, incontinence and oculomotor paralysis. All symptoms progressively regressed. Computed tomography showed transient low-density areas in the white matter. The main manifestations and the physiopathological mechanisms (transport of the parasite through the bloodstream, immuno-allergic reaction) of cerebral trichinosis are discussed.
