To recognize the most important imaging findings of non-neoplastic conditions of the duodenum. To be aware of the most frequent imaging appearances of duodenal neoplasms.  

The duodenum, being the first section of the small intestine, has some peculiarities that make it prone to a variety of conditions, either neoplastic or non-neoplastic. In this pictorial essay we will review the most frequent tumors of the duodenum (adenocarcinoma; lymphoma; GIST; lipoma; metastasis) and also some rare ones (Brunner's gland hamartoma; juvenile polyposis), focusing mainly on CT and upper gastrointestinal series findings. We will also discuss imaging findings of non-neoplastic conditions, such as congenital (situs inversus; malrotation; diverticula), traumatic (iatrogenic rupture; hematoma), inflammatory (groove pancreatitis; duodenitis; celiac disease; Crohn's disease; fistulas) and other emergency situations (gallstone ileus; afferent loop syndrome; internal hernia; varices; superior mesenteric artery syndrome). We will review all these conditions in alphabetical order, with at least one condition for each letter of the alphabet, in a two-part educational exhibit (part I - from letter A to letter K and part II - from letter L to letter Z).
