Choledochal cysts are rare congenital malformations, comprising of dilatation of the biliary tree of different localization. Classically, classification of choledochal cysts describes five variants of the disease. Type VI choledochal cyst is considered by many authors as the sixth variant of this classification and is described either as a dilatation of the cystic duct or as a cystic duct cyst. We present a rare case of cystic duct dilatation that presented with acute cholangiopancreatitis and a clinical picture consistent of a choledochal cyst in a 10-year-old female patient. Cholecystectomy with excision of the cystic duct was performed. Histopathologic examination did not reveal any findings consistent with choledochal cyst. Based on these findings we speculate that in our case the dilatation of the cystic duct is a variant to type VI choledochal cyst, based on the fact that no cystic-like malformation has been identified in histology. We provide details of the pre-operative work-up and compare them with intraoperative findings in order to increase awareness of the condition.
