A 45-year-old chronic alcoholic male presents with acute severe epigastric pain radiating to the back. Contrast-enhanced computed tomography (CECT) of the abdomen performed on day 3 of illness reveals a well-defined collection in the lesser sac with a thick, enhancing wall, located adjacent to the body and tail of the pancreas. There is no internal solid component. What is the most accurate imaging diagnosis for this lesion?
- A.Acute necrotic collection
- B.Pancreatic pseudocystCorrect answer
- C.Walled-off necrosis (WON)
- D.Serous cystadenoma
Solution
According to the revised Atlanta classification of acute pancreatitis, fluid collections are categorized based on time and the presence of necrosis. A pancreatic pseudocyst is a fluid collection surrounded by a wall of granulation tissue lacking an epithelial lining, typically developing at least 4 weeks after an episode of interstitial edematous pancreatitis. It appears as a well-defined, homogeneous fluid-density collection with a uniformly enhancing wall and no solid debris.
