Anomalous radiological and clinical demonstration of gallbladder duplication in an asymptomatic pregnant female.

Gallbladder duplication is an uncommon congenital anatomical deviation encompassing a number of variants. The morphological difference occurs during budding of the hepatic diverticulum. We report the case of an asymptomatic pregnant woman who was incidentally found to have a large subhepatic cyst on ultrasound. The case highlights the difficulty in diagnosing large gallbladder duplication and the different radiological imaging available to surgeons to aid in mapping such anatomical variants. We propose that this case holds valuable lessons for both radiologists and surgeons when considering the differential diagnosis and management of large hepatobiliary cysts.
