Abstract

Choledochal cysts are congenital or acquired disproportionate dilatations of any portion of the bile ducts, more commonly found to occur in the extrahepatic bile ducts. The incidence of choledochal cysts is rare, estimated to lie between 1 in 100,000 or 150,000 people in Western countries. However, the incidence is reported to be higher in Asian population. They are found to occur more frequently in females with a 4:1 female to male preponderance. Although most cases are usually diagnosed in infancy and childhood, up to 25% of cases are diagnosed in adulthood. In this pictorial review, we present cases from our institute that have been diagnosed and classified according to the Todani’s classification.
