Tumor and tumor-like lesions of duodenum: CT and barium imaging features.
Neoplasms of the duodenum, either primary or secondary, are uncommon. However, imaging diagnosis for presurgical evaluation is extremely important due to complex regional anatomy. Computed tomography (CT) and barium-based double contrast examination (UGI series) are most frequently employed to evaluate the tumor invasion and intraluminal mucosal pattern. In this pictorial review, the CT and UGI series imaging features of benign and malignant duodenal tumors and tumor-like lesions are demonstrated and discussed.
