Pancreatic Pseudocyst

Description

Centered in the upper abdomen, the pancreas appears in anterior aspect with its head nestled in the C-loop of the duodenum, the neck crossing the midline, and the body and tail extending leftward toward the splenic hilum. A prominent pancreatic pseudocyst expands from the gland surface, displacing the surrounding contour and emphasizing the lobulated exocrine parenchyma. Superior and slightly right-sided, the gallbladder is indicated in close relation to the pancreatic head region through the extrahepatic biliary tract, where the common bile duct courses toward the ampulla. Orientation is clear. Pseudocysts most often follow acute pancreatitis or pancreatic trauma, when enzyme-rich fluid collects and becomes walled off by granulation and fibrous tissue rather than true epithelium. An anterior representation like this helps explain why large collections in the lesser sac can compress the posterior wall of the stomach, narrow the duodenum, or obstruct the distal common bile duct, producing early satiety, gastric outlet symptoms, or painless jaundice. It also frames the procedural logic of endoscopic cystogastrostomy versus percutaneous drainage, decisions that depend on whether the collection apposes the stomach or tracks along retroperitoneal planes. Use this asset for teaching pancreatic anatomy and pancreatitis complications in GI blocks, surgery clerkship slide decks, or radiology-pathology correlation modules that introduce CT and ultrasound appearances of peripancreatic fluid collections. The clear separation of gland, cyst cavity, and adjacent biliary anatomy also suits patient education sheets and review chapters discussing pancreatitis, biliary obstruction, and timing of intervention.
