A 43-year-old Korean woman with biliary ascariasis accompanied by cholelithiasis is reported. Her chief complaints were abdominal pain, nausea, and vomiting. She had the past history of several attacks of abdominal pain in her childhood. Biliary stones were recovered from the left hepatic duct after cholecystectomy, which contained degenerated cuticle or body wall, and numerous eggs of Ascaris lumbricoides. It is strongly suggested that the biliary stones were formed from the dead Ascaris worm(s). This is a rare case of biliary ascariasis during the recent 5 years in Korea.

Obstruction of the left duct was somewhat relieved to show tubular dilatation, however, complete patency of the duct is not recognizable.
