Benign small bowel tumors are rare. If those with malignant potential are excluded, a small group of truly benign lesions remains. Fifty-six cases of these small bowel tumors were analyzed for clinical data, pathologic diagnosis, number, size, location, and radiologic appearance. Lesions included lipoma, myoepithelial hamartoma, Peutz-Jeghers hamartoma, neurogenic tumors (including gangliocytic paraganglioma), Brunner's gland abnormalities, and inflammatory fibroid polyp. Location, number, and radiographic morphology can be helpful in reaching a more specific diagnosis. Age of patient and size of tumor may be helpful in the differential diagnosis; however, sex of the patient and clinical symptoms are not.
良性小肠肿瘤较为罕见。若排除具有恶性潜能的肿瘤，剩下的是一小部分真正的良性病变。对56例此类小肠肿瘤的临床资料、病理诊断、数量、大小、位置及影像学表现进行了分析。病变包括脂肪瘤、肌上皮错构瘤、黑斑息肉病错构瘤、神经源性肿瘤（包括神经节细胞副神经节瘤）、布伦纳腺异常及炎性纤维性息肉。位置、数量及影像学形态有助于做出更明确的诊断。患者年龄和肿瘤大小可能有助于鉴别诊断；然而，患者性别及临床症状则无助于鉴别诊断。
