[Trichinellosis with neurological complications. Case report and short overview].

A 53-year-old, previously healthy man developed persistent diarrhea 4 days after ingestion of smoked but uncooked pork sausages in the Southern Tyrol. On his return to Switzerland he ate the same sausages and was admitted to hospital with migrating muscle pain, fever and chills. While fever and diarrhea soon regressed, the patient exhibited neurologic symptoms and change of character. The leukocyte count was 14 000/mm3 with 39% eosinophils. 40 days after hospitalization a second muscle biopsy established the diagnosis of Trichinella spiralis infection. At the same time, serologic tests were positive for Trichinella spiralis. Epidemiology, parasitology, symptomatology, diagnosis, therapy, prophylaxis and prognosis of trichinellosis are briefly discussed.
