Fig. 5

Grade V acute pancreatitis with modified CTSI (severe score 10). a CT scan shows almost more than 30% of the necrotic pancreatic tissue with the thrombosed splenic vein (yellow arrow), fluid collection in the retromesenteric plane (white star in a, b, and f), lateroconal plane (red arrow), and retrorenal plane (dotted blue arrow). Further, the pancreatic inflammation extends into both subfascial planes (green arrow in b and e). The retromesenteric plane and retrorenal plane have merged into the combined interfascial planes (yellow star in b, e, and f). c, d CT scan at a lower level shows the caudal extension of the fluid collection reaching the prevesical space (yellow arrows in d and e) and presacral space (white filled arrow in d) via the combined interfascial plane. f Sagittal view shows clearly the combined interfacial plane (yellow asterisk). This patient died from multiple organ failure dysfunction syndrome
