Correct answer: A. Foramen of Winslow (epiploic foramen)
Explanation
The lesser sac (omental bursa) is accessed through the epiploic foramen of Winslow, located posterior to the hepatoduodenal ligament (which contains the portal triad). Its boundaries are the hepatoduodenal ligament anteriorly, inferior vena cava posteriorly, caudate lobe of liver superiorly, and first part of the duodenum inferiorly. Pancreatic pseudocysts may present in the lesser sac because of its close anatomical relationship with the pancreas.
