Case Discussion
Features may consistent with type Ia choledochal cyst. Although age-related and cholecystectomy-related biliary dilatation could be considered in differential list. No prior imaging was available for comparison.
Choledochal cysts represent congenital cystic dilatations of the biliary tree. Diagnosis relies on the exclusion of other conditions (e.g. tumor, gallstone, inflammation) as a cause of biliary duct dilatation.
