A 74-year-old woman with a history of rectal carcinoma underwent whole body combined positron emission tomography/computed tomography (PET/CT) scanning for staging. Diffuse intense FDG uptake was seen in the distended infrarenal inferior vena cava (IVC) extending to the bilateral common iliac and left external as well as internal iliac veins. Heterogeneous hyperdense material was seen on the corresponding CT scan, suggesting tumor thrombus. Tumor thrombus shows increased FDG uptake resulting from the increased glycolytic rate in malignant cells.
一名有直肠癌病史的74岁女性接受了全身正电子发射断层扫描/计算机断层扫描（PET/CT）以进行分期。在扩张的肾下腔静脉（IVC）中可见弥漫性强烈的氟代脱氧葡萄糖（FDG）摄取，该静脉延伸至双侧髂总静脉以及左侧髂外静脉和髂内静脉。在相应的CT扫描上可见不均匀的高密度物质，提示肿瘤血栓。肿瘤血栓显示FDG摄取增加，这是由于恶性细胞中糖酵解速率增加所致。
