CHOLEDOCHAL CYST

Choledochal cysts are rare congenital abnormalities of the hepatobiliary system, classified by cystic dilatation of the common bile duct, usually requiring surgery after birth. Although they occur most commonly in childhood and infancy, they have been reported antenatally and in patients up to 80 years old (1-3).   It is more common in females (1male:1.5-3.5 female). More common in the Asian population.
