title: Duodenal duplication cysts of ampulla of vater containing stone.
abstract: Duodenal duplication cysts are rare congenital malformations. Most symptomatic cases are diagnosed in children and usually present with obstructive findings or bleeding symptoms. Treatment traditionally involves surgical resection, which can be often difficult because of the close proximity of the cysts to the papilla and bilopancreatic confluence. Endoscopic therapy has been used as an alternative to open surgery in a few selected cases. We report a case with a duodenal duplication cyst containing a brown pigmented stone within the cystic lumen. He was visited because of sudden right upper quadrant abdominal pain. An abdominal computed tomography revealed the presence of a cyst with a stone, which was finally removed by endoscopic resection.
