A case report: Type I choledochal cyst induced pancreatitis in a 15-month-old child

We present a case of a well-appearing 15-month-old boy with vomiting, diarrhea, and jaundice. Differentiation of an acute obstructive cholestasis from other causes of jaundice is important. This child’s evaluation included an ultrasound and computed tomography scan, which revealed a choledochal cyst, a congenital dilation of the extrahepatic portion of the biliary tree with secondary pancreatitis. The patient was treated surgically by excision of cyst. Choledochal cyst, although rare, needs to be considered in the differential diagnosis of obstructive jaundice by emergency physicians, as delays in diagnosis can cause complications and increase morbidity.
