Duplication cyst of the duodenum in the adult.
A duodenal duplication cyst in a 45-year-old male is reported. A hypotonic duodenography showed a smooth spherical defect in the descending portion of the duodenum. A fiberoptic duodenoscopy disclosed a smooth well-defined tumor which was located orally from the ampulla of Vater. A retrograde pancreatocholangiography indicated the tumor was not in communication with the pancreatic duct or biliary tract. At operation, a cystic spherical mass, 3 cm in diameter, was located in the posterior wall of the duodenum corresponding to the above described diagnosis. The combination of a greater awareness of this condition as well as improved X-ray and endoscopic techniques has made preoperative diagnosis more accurate.
