Figure 23a. Peripancreatic varices in a 71-year-old man with elevated liver enzyme levels. (a) Arterial phase CT scan shows how low-attenuation peripancreatic varices (long arrow) in the region of the pancreatic head (short arrow) can simulate a pancreatic mass. Arrowhead indicates the second portion of the duodenum. (b) On a venous phase contrast-enhanced CT scan, the varices (long arrow) are more clearly distinguished from the pancreatic head (short arrow). Arrowhead indicates the duodenum.
