Abstract
Small bowel tumors are rare malignancies in humans. Despite this rarity, their early
diagnosis and classification is crucial for further therapy management. Therefore,
radiologic imaging is of central importance. In our review, the most common entities
adenocarcinoma, neuroendocrine tumor, small intestinal lymphoma, gastrointestinal
stromal tumor (GIST) and small intestinal metastases are presented with their specific
characteristics and distinguishing features. In addition, key aspects for radiological
reporting as well as distinction from inflammatory alterations as the most common
differential diagnosis are discussed.
