Where is the most common location of a pancreatic pseudocyst?

• A. Lesser peritoneal sac
• B. Greater sac
• C. Pancreatic head region
• D. Splenic hilum

Answer: (D)

Fluid from the pancreas after pancreatitis most commonly collects in the lesser sac, the space behind the stomach. The pancreas sits right next to the posterior stomach and near the epiploic foramen, so leaked enzymes and inflammatory fluid tend to pool there and become walled off, forming a pseudocyst. That makes the lesser sac the typical location. The greater sac is the main peritoneal cavity and is less likely to harbor a localized pancreatic pseudocyst. While a pseudocyst can extend toward the pancreatic tail and reach the splenic hilum, that area is less commonly the primary site than the lesser sac.
