Calcification of the pancreas indicative of chronic pancreatitis.

Marked peripancreatic inflammatory change with fluid extending into the small bowel mesenterytransverse mesocolon and down into the pelvis. Some areas of focal reduced enhancement. Bilateral pleural effusions. 

Chronic left-sided hydronephrosis with renal cortical thinning.

Case Discussion

It is likely that a peripancreatic collection will develop. These are often amenable to percutaneously drainage under CT guidance, but usually, do not require drainage in the acute setting.
