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.

CT scan: sagital intra and extra hepatal duct, patients with Choledochal Cyst type IV: (A) The axial cut shows the dilation of the intra and extrahepatal ductus, (B) The axial cut shows the dilation of the intahepatal ductus, (C) The coronal cut shows the dilation of the intahepatal ductus, size of the lesion has not increased, the wall is not thickened, and the edges are regular. No masses or stones are visible. The extrahepatic bile duct is dilated, with a cystic lesion containing bile sludge, measuring approximately 6.25 × 7.14 × 12.40 cm, located in the proximal to distal common bile duct.
