A case of choledochal cyst type IV

Abstract

A choledochal cyst (CC) or biliary cyst is a congenital or acquired anomaly affecting the biliary tree. It involves the dilation of the biliary tree that could affect the extrahepatic and/or the intrahepatic segments. A choledochal cyst (CC) has traditionally been considered as a cystic dilation of the extrahepatic bile duct. The incidence of choledochal cysts is high in the Asian population with a female predominance. Choledochal cysts can present at any age, including infancy. However, 80% of choledochal cysts are diagnosed in the first decade of life, with cholestasis being the most common sign in infants, and cholangitis or pancreatitis being less common. Radiological and endoscopic imaging is the cornerstone of CC diagnosis. We report a case of 16 years old patient with choledocal cyst. The case has distinct clinical signs that are easily recognizable.
