Ectopic Gallbladder Mimicking Choledochal Cyst on Hepatobiliary Scintigraphy

Area of Science:

• Gastroenterology
• Pediatric Surgery
• Diagnostic Imaging

Background:

• The gallbladder is typically found in the liver's gallbladder fossa.
• Choledochal cysts are dilations of the common bile duct, usually located posteromedially.

Observation:

• A 10-year-old girl presented with an ectopic gallbladder.
• Hepatobiliary scintigraphy suggested the gallbladder anomaly resembled a choledochal cyst.

Findings:

• The ectopic gallbladder's location mimicked a choledochal cyst on hepatobiliary scintigraphy.
• This presentation is atypical for gallbladder anatomy.

Implications:

• This case underscores the need to include ectopic gallbladder in the differential diagnosis of choledochal cysts.
• Accurate diagnosis is crucial for appropriate management of biliary tract anomalies in children.
