Abstract

Among the 5 different Todani subtypes of choledochal cyst, type II choledochal cyst is known to be the rarest. A 13-month-old female who had underlying congenital portal vein stenosis and portal hypertension presented sudden hematemesis and abnormality in liver function test. Upon evaluation with a liver ultrasonography, a 1.7 cm-sized cystic lesion near the common bile duct and duodenum was incidentally discovered, and further imaging with magnetic resonance cholangiopancreatography, upper gastrointestinal series, computed tomography, and percutaneous transhepatic cholangiography revealed type II choledochal cyst. The patient underwent choledochal cyst excision with Roux-en-Y hepaticojejunostomy and had no acute postoperative complications.
