Abstract

A 46-year-old man was found to have an increased carcinoembryonic antigen level (25.7 μg/L) during physical examination, and an (18)F-FDG PET/CT scan was subsequently performed. The PET image indicated abnormal radioactivity levels in the left kidney, and the coregistered CT revealed compression of the left renal vein between the aorta and superior mesenteric artery. An ultrasonography was then performed, which revealed that the ratio between the renal hilum and the aortomesenteric left renal vein was 3.2. Therefore, the nutcracker phenomenon was diagnosed. When abnormal radioactivity is found in the left kidney on PET/CT scanning, the nutcracker syndrome should be considered.

摘要

一位 46 岁男性在体检时发现癌胚抗原水平升高（25.7μg/L），随后进行了（18）F-FDG PET/CT 扫描。PET 图像显示左肾放射性活性异常，同机 CT 显示左肾静脉在主动脉和肠系膜上动脉之间受压。随后进行了超声检查，发现肾门与腹主动脉和肠系膜上动脉之间的左肾静脉比值为 3.2。因此，诊断为胡桃夹现象。当 PET/CT 扫描发现左肾放射性活性异常时，应考虑胡桃夹综合征。
