Duodenal Diverticula Mimicking Cystic Neoplasms of the Pancreas: CT and MR Imaging Findings in Seven Patients

Abstract

When filled with only fluid, a duodenal diverticulum may mimic a cystic neoplasm in the head of the pancreas. Recognizing the location in which this entity characteristically arises and identifying small amounts of intradiverticular gas when it is present may aid in establishing the correct diagnosis in patients with duodenal diverticula.
