Double-balloon enteroscopy (DBE) and video capsule endoscopy are useful for the diagnosis of lymphoma in the small intestine. However, DBE cannot be safely performed in cases with passage disturbance due to wall thickening and stenosis. Additionally, video capsule endoscopy cannot be performed in such cases because of the risk of retention. Here, we report 4 cases of primary follicular lymphoma of the gastrointestinal tract that could be detected using (18)F-fluorodeoxyglucose positron emission tomography combined with computed tomography (PET-CT). The endoscopic findings of these 4 cases included lesions with wall thickening, which comprised macroscopically clusters of nodules, dense clusters of whitish granules or small nodules, fold thickening and ulcers with irregular margins that occupied the whole lumen with edematous mucosa. All patients fulfilled the World Health Organization grade 1 criteria. (18)F-fluorodeoxyglucose PET-CT can help predict the risks that may result from certain endoscopic examinations, such as DBE and video capsule endoscopy.
双气囊小肠镜（DBE）和胶囊内镜对于小肠淋巴瘤的诊断很有用。然而，由于壁增厚和狭窄导致的通道障碍，DBE 不能安全地进行。此外，由于滞留的风险，视频胶囊内镜也不能在这种情况下进行。在这里，我们报告了 4 例胃肠道原发性滤泡性淋巴瘤，这些病例可以通过（18）F-氟脱氧葡萄糖正电子发射断层扫描（FDG-PET）结合计算机断层扫描（CT）检测到。这 4 例的内镜检查结果包括壁增厚的病变，这些病变包括宏观上的结节簇、密集的白色颗粒或小结节簇、褶皱增厚和边缘不规则的溃疡，占据整个有水肿的黏膜的管腔。所有患者均符合世界卫生组织（WHO）1 级标准。（18）F-FDG-PET-CT 有助于预测某些内镜检查（如 DBE 和视频胶囊内镜）可能带来的风险。
