A 61-year-old man with previous history of lung adenocarcinoma underwent 2 F-FDG PET/CT investigations. The first for assessment of enlarged mediastinal lymph nodes revealed an area of increased FDG uptake in the sigmoid colon (located at the right pelvis). Colonoscopy showed a segmental area of ischemic sigmoid colitis, confirmed on histology postbiopsy. The asymptomatic man had no risk factors, and no specific treatment was administered, apart from supportive measures. One year later, there was no significantly abnormal uptake on PET/CT. Incidental ischemic colitis may be demonstrated with FDG and PET/CT needing no specific therapeutic measures for resolution.
一位 61 岁的男性，有肺腺癌既往病史，进行了 2 次 F-FDG PET/CT 检查。第一次用于评估纵隔淋巴结肿大，发现乙状结肠（位于右骨盆）有一处 FDG 摄取增加。结肠镜检查显示乙状结肠节段性缺血性结肠炎，活检后组织学证实。这位无症状的男性没有危险因素，除了支持性治疗外，没有给予特定的治疗。一年后，PET/CT 上没有明显异常摄取。FDG 可显示偶发性缺血性结肠炎，无需特定的治疗措施即可缓解。
