Combined necrosis complicating hemorrhage from acute necrotizing pancreatitis in a 28-year-old man. (A) An axial turbo spin-echo (TSE) T2-weighted fat-suppressed image shows apparent hypointense areas (arrow) in the pancreatic tail relative to the normal signal intensity of the parenchyma (P), compatible with necrosis coexisting hemorrhage. Extrapancreatic necrosis (asterisk) is also demonstrated. (B) An axial diffusion-weighted image (b=500 s/mm2) shows focal areas of restriction (arrow) in the body and marked non-restriction areas in the tail of the pancreas indicative of necrosis complicating acute-phase bleeding. (C) ADC map shows that the ADC value of necrosis complicating hemorrhage portion (0.76×10−3 mm2/s) is much lower than that of the adjacent gland (0.99× 10−3 mm2/s).
