Figure 2a. Images in a 62-year-old man with pathologically proved adenocarcinoma of the pancreatic head. (a, b) Transverse contrast material-enhanced CT scans obtained in the pancreatic phase demonstrate an ill-defined mass (* in a) that abuts both the gastroduodenal artery (arrow in a) and the medial wall of the duodenum. (c) Curved planar reformation of the pancreas shows a dilated distal pancreatic duct (arrows) that terminates at an ill-defined isoattenuating mass (*).

Figure 3a. Images in a 64-year-old woman with pathologically proved adenocarcinoma of the pancreas. (a) Transverse contrast-enhanced CT scan obtained in the pancreatic phase demonstrates an isoattenuating mass (*) in the body of the pancreas. A dilated distal pancreatic duct (left arrow) and distal pancreatic atrophy (right arrow) are seen. (b) Curved planar reformation of the pancreas shows distal pancreatic atrophy (arrow) and a dilated distal pancreatic duct terminating at an ill-defined isoattenuating mass (*).
