Hepatobiliary fascioliasis: Clinical and radiological features

ABSTRACT

Fascioliasis is a worldwide but unevenly distributed zoonosis caused by the trematode Fasciola hepatica that infects domesticated herbivores. Fasciolosis also occurs accidentally in humans by ingestion of metacercaria-laden freshwater or water plants. Human infections are common in developing countries and are not rare in Europe. The clinical course has been conventionally described in two phases an acute phase of hepatic parenchymal invasion of an immature worm larva [parenchy-mal phase] and a stationary phase after residence in the bile duct and production of eggs [ductal phase]. We report a 34 years old woman from Ilam, western Iran with hepatic disorder, RUQ pain, and jaundice. The diagnosis was made by sonography, CT scan and serologic studies. Serologic exam [ELISA] was positive and CT findings were compatible with fascioliasis
