Choledochal Cyst Associated with Cystic Duct Dilatation: Report of Three Cases

ABSTRACT

Traditionally, it has been accepted that choledochal cysts are cystic dilatations of the extrahepatic duct. The association of this anomaly with cystic dilatations of cystic duct is extremely rare. Here in three cases of choledochal cysts with cystic duct dilatations, unusual variant of choledochal cyst are described. In all three cases, MRCP showed that the dilated cystic duct communicates with a common duct through a wide opening.
