Small bowel cancer. Imaging features and staging

Abstract

Small bowel neoplasms are relatively rare. This article presents the imaging features of the most frequently encountered small bowel masses, with emphasis on adenocarcinomas and carcinoid tumors. The CT scan findings and correlative barium and angiographic studies of various small bowel tumors are illustrated. The staging of adenocarcinoma of the small intestine is addressed, with attention to the role of CT scans for radiologic staging.
