Acute pancreatitis: A pictorial review of early pancreatic fluid collections

Figure 11 Schematic diagram of acute necrotizing pancreatitis, and extrapancreatic fluid and computed tomography of a patient. A: Schematic diagram of acute necrotizing pancreatitis and extrapancreatic fluid with extension within the pancreatic parenchyma (arrow); B: A 56-year-old woman with acute necrotizing pancreatitis. Axial contrast-enhanced computed tomography image in the late arterial phase shows a peripancreatic homogeneous collection (arrowheads). It may be misinterpreted as “acute peripancreatic fluid collection.” However, note the peripancreatic fluid extends into the parenchyma of the head and neck of the pancreas (arrow). Therefore, it should be diagnosed as an “acute necrotic collection.” P: Pancreas; APFC: Acute peripancreatic fluid collection; ANC: Acute necrotic collection.
