The choledochal cysts, which refer to the cystic dilatation of the biliary duct, are rare lesions generally seen in children. Choledochal cyst of the cystic duct is an uncommon entity. Often, it is associated with the choledochal cyst of the rest of the biliary tree. Isolated cystic duct choledochal cyst is quite rare. Most of these lesions have been recognized only on surgery. Modern cross-sectional imaging methods have facilitated preoperative recognition and characterization of cystic duct cyst enabling formulation of appropriate management strategy. We report the imaging findings in three cases of choledochal cyst involving the cystic duct. All these cases were correctly diagnosed preoperatively. A review of cases reported in the literature and the role of imaging in guiding the management are also presented.
