[Liver fascioliasis with unusual abscess formation. Case report].

The case is reported of a 34-year-old Swiss who presented with signs of liver abscess after returning from South America. The symptoms regressed under trial treatment with a tissue amoebicide. The initial blood hypereosinophilia could be explained only 8 months later by the presence of eggs of Fasciola hepatica in the patient's faeces. Serological investigations were negative for amoebiasis an hydatid disease but positive for fascioliasis. The possibility of abscess formation by infestation with F. hepatica is discussed.
