Abstract:
Fasciola hepatica, a liver fluke of livestock, rarely presents as chronic biliary tract infection in humans. We report a 38-year-old woman from Ethiopia who presented with right upper quadrant pain and a dilated common bile duct on ultrasound and magnetic resonance cholangiopancreatography (MRCP) without other abnormalities. She was suspected to have type II sphincter of Oddi dysfunction. She underwent endoscopic retrograde cholangiopancreatography (ERCP) and had a fluke, diagnosed as Fasciola hepatica, in the common hepatic duct. This report confirms the diagnostic and therapeutic role of ERCP in the management of biliary fascioliasis, and highlights the need to include fascioliasis in the differential diagnosis of biliary pain in patients emigrating from areas where this infection is endemic.
