The walls of the second part of the duodenum are thickened with a small volume of free fluid; there are recognizable ectopic pancreatic islands with a similar degree of enhancement to the rest of the pancreas.

Paraduodenal pancreatitis is characterized by a history of excess alcohol and tobacco use in male patients, and a painful symptomatology. Histology analysis demonstrates granulomatous tissue, stromal proliferation, and ectopic pancreatic tissue within the duodenal wall. The epicenter of the inflammation is typically located between the duodenum, common bile duct and pancreas. The presence of cysts inside the inflamed duodenal wall allows distinguishing between a "cystic" (75%) and a "solid" variant of paraduodenal pancreatitis.
