Signs of acute pancreatitis are present in this post-contrast scan of the abdomen. The pancreas is swollen with indistinct margins and there is infiltration of the mesentery. The superior mesenteric artery is seen enhancing anterior to the left renal vein, with the superior mesenteric vein lying to its right.
 
This is another image from the same study. The superior mesenteric artery and vein are clearly identifiable anterior to the duodenum.
 
There has been significant deterioration in appearance since the previous study. The pancreatic head is swollen and formless, with indistinct margins. There is free fluid in the abdomen, around the liver and this extends into the left paracolic gutter. There are also inflammatory changes and a large amount of fluid within the mesentery. The superior mesenteric artery is demonstrated, with the superior mesenteric vein lying to its right.
 
An inferior image from the same study demonstrates an abnormal, enhancing vascular lesion, to the right of the superior mesenteric artery and vein. This pseudoaneurysm is also demonstrated in image 2c.
