title: [A case of alveolar hydatid disease in a dog: domestic animals as rare incidental intermediate hosts for Echinococcus multilocularis].
abstract: A 2-years old male Labrador retriever dog was presented with intermittent therapy-resistant diarrhoea, accompanied by vomiting, inappetence, apathy, and mild fever. The blood analysis showed an anaemia, neutrophilia, eosinophilia, and increased liver enzymes. Abdominal palpation was slightly painful. X-rays and echography revealed a severely enlarged liver with multiple cavernous structures. Histopathologic examination of liver biopsies showed a severe chronic granulomatous hepatitis with numerous parasitic cysts. Morphology of the cysts was compatible with the metacestode stage of Echinococcus multilocularis. The dog was only 2-years old at the time of diagnosis. Although alveolar hydatid disease of the liver is rare in dogs, it should be envisaged as a possible differential diagnosis in cases of space-occupying processes in the liver, even in young animals, as the incubation period of this disease in the dog can be considerably shorter than in humans.
