Ecografía y tomografía computarizada de la patología duodenal

This report describes and illustrates the CT and US findings for dif-ferent 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.
