title: [Cyst of the duodenum with termination of the bile and pancreatic ducts (author's transl)].
abstract: The radiological findings in a 27-year old female Turkish patient with a cyst in the wall of the duodenum are described. It caused a sharply demarkated, smooth thumb-print in the duodenum shown by barium meal. An intravenous and intra-operative cholangiogram caused filling of the cyst with contrast through the bile duct. The bile and pancreatic ducts terminated on the medial side of the cyst through the papilla of Vater. The size of the cyst varied, depending on its degree of filling with bile and pancreatic juice. Its position and morphology has been confirmed at operation. Histology showed an external cover of small bowel mucosa and an inner lining of small bowel mucosa interspersed with islands of gastric mucosa. The development of this cyst is explained as a developmental anomaly during recalisation of the embryonic duodenum.
