Walled‐off necrosis are mature collections of (peri)pancreatic necrosis encapsulated by an inflammatory wall that forms more than four weeks following onset of necrotizing pancreatitis. On CECT (Figure 3.4), walled‐off necrosis appears as a heterogeneous collection of liquid and solid necrotic tissue surrounded by a well‐defined rim. Like other local fluid collections, walled‐off necrosis may become infected.
