Despite these similarities with colon cancer, small-bowel adenocarcinomas (SBAs) tend to cluster away from the colon, toward the gastric end of the small intestine.Approximately 50% arise in the duodenum, 30% in the jejunum, and 20% in the ileum. Nonoperative Management of Penetrating Abdominal Trauma. Symptoms Non-Hodgkin and Hodgkin lymphomas frequently involve many structures in the abdomen and pelvis. Although the differential diagnosis for a small bowel tumor is extensive, various small bowel neoplasms have characteristic features at computed tomography (CT) that may aid in making a diagnosis. Small bowel adenocarcinoma may appear at CT as an annular lesion, a discrete nodular mass, or an ulcerative lesion. In most cases, barium exams, CT scanning, and MRI are the methods of choice in this setting.
