[A probable case of alveolar echinococcosis in Normandy, France].

Echinococcus multilocularis induced liver infection was diagnosed in a Moroccan patient. Diagnosis was based on CT scan results and Western Blot test. Contamination probably occurred in France, in the Cherbourg area where the patient travelled frequently and ate wild berries. This case and other recently reported cases outside the usual endemic areas (Besançon and the Massif Central) suggest that the Echinococcus multilocularis epidemic has moved towards the west of France. French gastroenterologists should be aware of this parasitic disease.
