Case Discussion
CT features of a hetrogeneously enhancing mass bulging within the lumen of the 2nd duodenum with a "double duct sign" suggestive of an ampullary tumor.
Ampullary tumor arise from the glandular epithelium of the ampulla of Vater. It may be either benign (adenoma) or malignant (carcinoma).
