abstract: We report a case of duodenal primary non-Hodgkin lymphoma classified as a polymorphic B lymphoma with a low degree of malignancy. It was studied by ultrasound, computed tomography and simple contrast study. We review the radiologic appearance, sites of origin, and the role of Imagiology in staging and differential diagnosis.
