Özet
Small bowel tumors are rare and account for approximately 3% of all gastrointestinal tumors. Primary small bowel cancer involving various histological tumors, such as adenocarcinoma, malignant lymphoma, gastrointestinal stromal tumor, and sarcoma. This may, in part, be due to the small bowel lesion identification in an increasing number of cross-sectional imaging studies performed for other indications, as well as the increased use of advanced imaging techniques to assess specifically for small bowel disease. Diagnosis is a challenge owing to nonspecific clinical manifestation, rare occurrence, and low index of clinical suspicion. Yet, various small bowel neoplasms have characteristic imaging features at CT and MRI when optimal distention of the small bowel is achieved, correlating well with features seen in gross specimens. Most small bowel tumors are clinically silent for long periods.
