title: Massive dilatation of the common bile duct resembling a choledochal cyst.
abstract: We present an unusual case in which an impacted calculus at the lower end of the common bile duct produced massive dilatation. This resulted in a confusing picture of choledochal cyst on abdominal ultrasound and endoscopic retrograde pancreatography. The common bile duct returned to normal size after removal of the stone.
