Acute pancreatitis: A pictorial review of early pancreatic fluid collections

Figure 9 Schematic diagram of necrotizing pancreatitis and computed tomography image of a patient. A: Schematic diagram of necrotizing pancreatitis (peripancreatic necrotic type). Acute necrotic collection involving peripancreatic fat only (arrows) is seen; B: A 58-year-old woman with necrotizing pancreatitis (peripancreatic necrosis only). Axial contrast-enhanced computed tomography image in the venous phase shows normal pancreatic parenchymal enhancement without definite necrosis. A peripancreatic collection may be misdiagnosed as “acute peripancreatic fluid collection.” However, multiple heterogeneous, nonliquid adipose components (arrows) are revealed among the collection. For this reason, it should be considered as acute necrotic collection. P: Pancreas; APFC: Acute peripancreatic fluid collection; ANC: Acute necrotic collection.
