Choledochal cyst with bile duct dilatation: sonography and /sup 99m/Tc IDA cholescintigraphy
Three cases of choledochal cyst associated with intrahepatic biliary dilatation are presented. Findings on sonography included a large cystic mass in the porta hepatis separate from the gallbladder; a dilated common hepatic or common bile duct entering directly into the cyst; and smaller cystic masses of dilated central intrahepatic ducts. All three patients underwent operation with intraoperative cholangiography. Two patients had /sup 99m/Tc IDA cholescintigraphy which confirmed the diagnosis of choledochal cyst by demonstrating filling of the cyst with stasis and delayed intestinal activity. The accurate preoperative diagnosis of choledochal cyst, made by sonography combined with /sup 99m/Tc IDA cholescintigraphy, obviated invasive studies.
