Development and Congenital Anomalies of the Pancreas
(a) Normal development of the pancreas. The ventral pancreatic anlage is initially paired, with the left lobe subsequently disappearing during development. The ventral pancreatic anlage fuses side by side with the dorsal anlage. (b) Choledochal cysts can occur when the left ventral anlage persists and disturbs normal bile duct recanalization. (c) Non dilation-type APBJ occurs when the ventral anlage fuses with the dorsal anlage in an oblique position. RVP, right ventral pancreatic anlage; LVP, left ventral pancreatic anlage; DP, dorsal pancreatic anlage.
