Abstract

Given its crucial location at the crossroads of the gastrointestinal tract, the hepatobiliary system and the splanchnic vessels, the duodenum can be affected by a wide spectrum of abnormalities. Computed tomography and magnetic resonance imaging, in conjunction with endoscopy, are often performed to evaluate these conditions, and several duodenal pathologies can be identified on fluoroscopic studies. Since many conditions affecting this organ are asymptomatic, the role of imaging cannot be overemphasized. In this article we will review the imaging features of many conditions affecting the duodenum, focusing on cross-sectional imaging studies, including congenital malformations, such as annular pancreas and intestinal malrotation; vascular pathologies, such as superior mesenteric artery syndrome; inflammatory and infectious conditions; trauma; neoplasms and iatrogenic complications. Because of the complexity of the duodenum, familiarity with the duodenal anatomy and physiology as well as the imaging features of the plethora of conditions affecting this organ is crucial to differentiate those conditions that could be managed medically from the ones that require intervention.
