Cystic dilatation of cystic duct with associated carcinoma gall bladder: A rare entity

Choledochal cysts are rare congenital biliary tree anomalies characterized by all or part of extrahepatic or intrahepatic biliary duct dilatation. Todani et al. modification has classified choledochal cysts into five basic subtypes. Most of the choledochal cysts are encountered in children. Approximately 20% of the cysts can be present in adults with a male:female ratio of 1:4. Modified Todani classification of choledochal cysts is most widely accepted, but it does not include isolated cystic dilatation of the cystic duct.We describe here a case of a 34 years old male with cystic dilatation of cystic duct and associated carcinoma of the gall bladder presenting with epigastric pain.
