Necrotizing pancreatitis complicated by hemorrhage


Key teaching points:

  1. Hypoenhancing (necrotic) areas of the pancreas have increased conspicuity on narrow (liver) windows
  2. When there is necrotizing pancreatitis, the collections about the pancreas are referred to as "acute necrotic collections" until around week 4 when they are organized, and then are referred to as "walled-off necrosis"
  3. Necrotizing areas can be complicated by hemorrhage, and is evidenced by increasing complex appearance on CT or T1W hyperintensity on MRI.
