Patient and Methods: Thirty patients suspected to have small bowel neaoplasms were examined with 64 MDCT and underwent surgical exploration. Result: Contrast enhanced MDCT enterography easily diagnosed twenty patients with small intestinal neoplasms which were confirmed with surgical exploration and histopathological results. Conclusions: Our study has been proved that MDCT can be used as a front-line imaging modality for detection of small bowel neoplasms, regarding its ability to show intraluminal, mural and extraintestinal lesions with their characteristic density and features to successfully differentiate between the different neoplasms and sometimes stage them. However, operative exploration with curative resection or biopsy is still the confirmatory diagnostic method.展开更多
