[Echinococcus multilocularis causing extensive biliary obstruction (author's transl)].

Infection of man by Echinococcus multilocularis occurs relatively seldom, most commonly localizing in the liver in the manner of a malignant tumour. A case of alveolar hydatid disease is reported presenting with extensive biliary obstruction, and a large cavitation in the liver due to necrosis. A review of epidemiology, clinical and roentgenological findings is given.
