The vaccination immune response may induce false-positive F-FDG PET/CT uptake.
An extended supraclavicular lymph nodal activation after coronavirus disease 2019 (COVID-19) vaccination revealed on F-FDG PET/CT mimics a Virchow nodule in a patient with medical history of well-differentiated appendicular adenocarcinoma.
This case highlights a nodal activation beyond axillary area and the importance of documenting vaccination history at the time of scanning to avoid false-positive results.
疫苗接种免疫反应可能会导致氟代脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（F-FDG PET/CT）摄取出现假阳性。
1例有高分化阑尾腺癌病史的患者，在接种2019冠状病毒病（COVID-19）疫苗后，F-FDG PET/CT显示锁骨上淋巴结广泛激活，类似魏尔啸淋巴结。
该病例突出了腋窝以外区域的淋巴结激活情况，以及扫描时记录疫苗接种史以避免假阳性结果的重要性。
