Evolution of fascioliasis after eating wild watercress.
Fascioliasis is rarely reported in humans although it is endemic in sheep and cattle. We describe the illness of a 60-year-old widow who ate wild watercress which is the usual source of infestation. Laparotomy for suspected liver abscesses revealed necrotic tracts on the surface of the liver left by the invasion of numerous flukes. Diagnosis was made during the latent phase by the detection of serum antibody to fasciola hepatica antigen obtained from a sheep. Symptoms returned during the cholestatic phase. Mature flukes were then present in the large bile ducts and ova appeared in the stools. Symptoms resolved twelve weeks after presentation.
