title: Duplication of the duodenum extending into liver.
abstract: A large intrahepatic duodenal duplication connected to the duodenum by two openings is described. No similar cases of intrahepatic cysts have been found in the literature. The patient, a forty-four year old woman, had recurrent and numerous bouts of right upper quadrant pain over many years before the intrahepatic portion of the cyst was drained by a Roux-en-Y anastomosis after the connections with the duodenum had been excised.
