Abdominal ultrasonography showed a non-homogeneous mass measuring 32 mm in diameter between the pancreatic head, descending duodenum, and common bile duct, as well as swelling of the pancreatic head (Figure 1).
Abdominal CT shows swelling of the pancreatic head and a non-homogeneously enhanced low-density area between the pancreatic head, the duodenum, and common bile duct (A). The head of the pancreas is swollen and enhanced on contrast CT scan (B).

Computed tomography (CT) revealed swelling of the pancreatic head and a non-homogeneously enhanced, low-density area between the pancreatic head, descending duodenum, and common bile duct (Figure 2A). The head of the pancreas was enhanced on contrast CT scan and peripancreatic vessel encasement was not seen (Figure 2B).
MR images show a mass between the pancreatic head, the duodenum, and common bile duct. The mass is hypointense on T1-weighted image (A) and hypointense relative to the pancreatic head on T2-weighted image (B). T1-weighted images on dynamic study show the medial wall thickening of the descending duodenum and several small cysts in the groove (C) and thickened duodenal wall (D).

MR images revealed a mass between the pancreatic head, duodenum, and common bile duct that was hypointense on T1-weighted images (Figure 3A) and hypointense relative to the pancreatic head on T2-weighted images (Figure 3B). T1-weighted images, we observed the medial wall thickening of the descending duodenum, several small cysts in the groove and thickened duodenal wall on enhanced images (Figure 3C, 3D).
