Linear EUS showing an inhomogeneous hypoechoic mass with irregular borders in the head of the pancreas. The echotexture of the pancreatic parenchyma appears heterogeneous with a coarse reticular pattern. A single pancreatic duct (PD) with a maximal diameter of 4 mm could be delineated in the head of the pancreas, appearing uniform with anechoic margins. A patent portal vein (PV) was also depicted bellow the PD with no evidence of tumor invasion.

The stenosed bile duct wall appeared thickened (>3 mm), while no abnormalities were noted in the pancreatic ductal system (Figures 1 and 2).
Linear EUS showing a markedly inhomogeneous pancreatic body parenchyma. The ultrasound wave was unable to delineate anatomical structures corresponding to either the main or the secondary pancreatic duct.

The stenosed bile duct wall appeared thickened (>3 mm), while no abnormalities were noted in the pancreatic ductal system (Figures 1 and 2).
Postoperative followup dynamic magnetic resonance T1-weighted imaging of the remnant pancreas depicting the main as well as the secondary pancreatic duct (arrow and arrowhead resp.) draining the remaining dorsal pancreas at the level of the double pancreaticojejunal anastomosis.

Postoperative follow-up dynamic magnetic resonance imaging of the remnant pancreas depicted the main as well as the secondary pancreatic duct draining the remaining dorsal pancreas at the level of the double pancreaticojejunal anastomosis, allowing the confirmation of diagnosis of bifid pancreatic duct (Figure 3).
