Findings Discussion Gallbladder
duplication is a well-known entity with an incidence at autopsy reported
of 2.5:10,000. Boyden's classic description defines gallbladder
duplication as an embryologic abnormality in biliary tract development
resulting in two separate gallbladder cavities, each with a cystic duct. The
gallbladder has been found on the left side (to the left of the ligamentum
teres) in subjects in whom there was no general tranposition of the
thoracic and abdominal viscera. The
gallbladder may be intrahepatic or beneath the left lobe. Ectopic sites
include retrohepatic positions, or in the anterior abdominal wall or
falciform ligament, they may be suprahepatic or transversely position,
floating, or retroperitoneal. They may be in the midline anterior
epigastric above the left lobe or suprahepatic above the right hepatic
lobe. Several
anomalies have been associated with gallbladder duplication including
forgut malformations and aberrant hepatic and mesenteric vessels. The
right and left divisions of the hepatic duct sometimes continue separately
for some distance within the lesser omentum. The common bile duct may open
separately from the pancreatic duct into the duodenum. There may be one or
two distinct duodenal papillae. Anomalous pancreatic tissue is
occasionally found in the wall of the gallbladder. Differential
