Fascioliasis is a zoonotic infection of herbiviores, occasionally affecting humans who ingest fresh water plants. We report a case of a young woman who presented to our center with vague abdominal discomfort & discovered on abdominal ultrasound to have gall stones & dilated common bile duct. She was scheduled for ERCP which revealed a large number of fasciola worms draining from the common bile duct to the duodenum.
