Evidence of pancreatitis is seen as pancreatic edema, peripancreatic fatty haziness, and retroperitoneal fascial thickening on the left side. The pancreatic body does not show normal enhancement despite enhancing pancreatic head or distal tail, suggestive of pancreatic necrosis (more than 50%, score 6). At least one acute fluid collection (likely acute necrotic collection) is visible in the lesser sac (Balthazar score 3, CT severity index 9). At least one stone at the pancreatic portion of the CBD and another one at the distal cystic duct just before insertion to the CBD, and several gallstones are visible, in favor of biliary pancreatitis.
