Figure 9a.   Choledochal cyst (type IC) with biliary atresia in a female neonate with jaundice. (a) Sagittal sonogram shows a fusiform choledochal cyst (arrow) involving the common bile duct. The surrounding hepatic echotexture is coarse. The gallbladder (not shown) was tiny. (b) Intraoperative cholangiogram demonstrates a small gallbladder (GB) and choledochal cyst (CC). (c) Intraoperative cholangiogram obtained after a stronger injection of contrast material reveals atretic intrahepatic biliary ducts consistent with biliary atresia. A hepatobiliary scan (not shown) showed no excretion of the radiopharmaceutical.
