Classifying choledochal cysts using hepatobiliary scintigraphy

Ectopic Gallbladder Mimicking Choledochal Cyst on Hepatobiliary Scintigraphy

The gallbladder is generally located at the anterolaterally situated gallbladder fossa on the undersurface of the liver, whereas choledochal cyst, as a dilation of the common bile duct, is located more posteromedially. We reported an ectopically located gallbladder, which appeared to be a choledochal cyst on hepatobiliary scintigraphy in a 10-year-old girl.

Spontaneous rupture of a type IVA choledochal cyst in a young adult during radiological imaging

A case of a 24-year-old male with jaundice and epigastric pain is reported. The patient underwent a thorough clinical, laboratory, and imaging investigation. Computerized tomography revealed a 9 cm×10 cm choledochal cyst. Magnetic resonance imaging and magnetic cholangiopancreatography were performed, during which he developed an “acute abdomen”, with radiological evidence of biliary peritoneal leak. Urgent surgery revealed rupture of the distended malformed common bile duct. A peritoneal drain was instilled and a more definitive surgical procedure was accordingly scheduled. Hepatobiliary scintigraphy following surgery verified these findings, as well as confirmed the adequacy of the urgent surgery. A combination of radiological and nuclear medicine techniques substantially contributes to the diagnosis of choledochal cyst rupture and the adequacy of surgical intervention.
