[Ultrasound and CT study of duodenal pathology].
The radiological evaluation of the duodenum has traditionally been based on barium transit studies; however, ultrasound (US) and computed tomography (CT) are becoming more important in the assessment of this portion of the intestine and the structures that surround it. This report describes and illustrates the CT and US findings for different entities that affect the duodenum, including diseases of the duodenum itself and those of neighboring organs that affect this portion of the small intestine. We classify the pathologies by etiology into congenital, traumatic, iatrogenic and foreign bodies, bezoars, hematologic, inflammatory and neoplastic. Moreover, we present the incidental duodenal and periduodenal findings in US and CT that radiologists should be familiar with given the widespread use of these techniques.
