Necrotizing pancreatitis - acute necrotic collection maturing into walled-off pancreatic necrosis
Presentation
Abdominal pain.
Patient Data
Acute pancreatitis is with pancreatic edema with large non enhancing parenchymal areas (necrotic), peripancreatic fluid (ANC) and fluid tracking within the anterior pararenal space.
Three week follow-up
Pancreatic parenchyma is replaced by large pancreatic and peripanreatic encapsulated collections with areas of hemorrhage.
Case Discussion
This collection makes the criteria for an acute necrotic collection and walled-off pancreatic necrosis as a complication of "necrotizing pancreatitis". It is not to be confused with pseudocyst, which occurs later than 4 weeks following interstitial edematous pancreatitis and is more uniformly round with enhancing margins.
