Parenchymal necrosis is seen as areas of nonenhancement in the pancreatic head (arrow) relative to normal enhancing pancreatic tissue more posteriorly (arrowhead). There is associated peripancreatic inflammatory stranding in the bilateral retroperitoneum and mesentery, as well as early acute necrotic collections (asterisk).
