Abstract:
Ascaris lumbricoides is one of the most common parasitic infestations of the gastrointestinal tract worldwide. The migration of Ascaris lumbricoides into the biliary tree is an uncommon but well-known complication of intestinal ascariasis and often results in biliary colic. A case of acute common bile duct obstruction caused by a roundworm in a 37-year-old woman, a North Korean defector, is reported. Ultrasonography showed no specific abnormal findings except acute cholecystitis and an intrahepatic biliary stone. However, the MDCT clearly demonstrated a linear filling defect in the common bile duct that led to the correct diagnosis. Biliary ascariasis should be considered in the differential diagnosis of upper abdominal pain of patients in populations at risk.
