A 46-year-old female underwent a fluorodeoxyglucose F-18 (FDG) positron emission tomography (PET) whole-body scan for tumor screening after showing no symptoms or signs. The PET images showed a large FDG-avid lesion in the left renal pelvis, with a maximum standard uptake value (SUV) of 10.7 at 1 hour and 3.9 at 3 hours. An abdominal computed tomography (CT) scan showed a 3.7-cm cystic lesion with a slightly irregular wall in the left kidney. The immediate impression was that of a complicated cyst. A histopathologic report after surgery confirmed a calyceal diverticulum. To the best of our knowledge, this is the first report of FDG uptake in a case of calyceal diverticulum.
一名46岁女性在未出现任何症状或体征的情况下，接受了氟代脱氧葡萄糖F-18（FDG）正电子发射断层扫描（PET）全身检查以进行肿瘤筛查。PET图像显示左肾盂有一个大的FDG摄取性病变，1小时时最大标准摄取值（SUV）为10.7，3小时时为3.9。腹部计算机断层扫描（CT）显示左肾有一个3.7厘米的囊性病变，壁稍不规则。初步印象是复杂囊肿。手术后的组织病理学报告证实为肾盏憩室。据我们所知，这是肾盏憩室病例中FDG摄取的首次报告。
