Acute pancreatitis: A pictorial review of early pancreatic fluid collections

Figure 10 Schematic diagram of necrotizing pancreatitis and magnetic resonance imaging of a patient. A: Schematic diagram of necrotizing pancreatitis (pancreatic parenchymal necrosis alone). The peripancreatic collections are homogeneous; B: A 47-year-old man with necrotizing pancreatitis complicated with haemorrhage. Magnetic resonance imaging axial T1WI image shows peripancreatic homogeneous fluid with greater hyperintense signal. For this reason, it may be misdiagnosed as “acute peripancreatic fluid collection.” However, the necrosis and haemorrhage (arrow) of the body and tail of the pancreas can be indicated. Therefore, the collection should be diagnosed as acute necrotic collection. P: Pancreas, N: Necrosis, H: Haemorrhage; APFC: Acute peripancreatic fluid collection; ANC: Acute necrotic collection.
