Benign uptake on 18F-FDG PET can be seen with inflammatory conditions. We report a case of an 86-year-old woman with successfully treated nasal melanoma who underwent routine follow-up 18F-FDG PET, day 6 after the second dose of Pfizer-BioNTech COVID-19 vaccine inoculated in the left deltoid muscle. 18F-FDG PET showed increase tracer uptake in the left deltoid muscle and in 2 normal-sized left subpectoral nodes. These findings were considered secondary to vaccination. With the current drive of global COVID-19 immunization, this case highlights the importance of documenting vaccination history at the time of scanning to avoid false-positive results.
18F-FDG PET 上的良性摄取可见于炎症性疾病。我们报告了一例成功治疗的鼻黑素瘤患者，该患者在左侧三角肌接种了辉瑞-生物科技公司第二剂 COVID-19 疫苗后 6 天接受了常规 18F-FDG PET 随访。18F-FDG PET 显示左三角肌和 2 个正常大小的左胸肌下淋巴结摄取示踪剂增加。这些发现被认为是疫苗接种的结果。随着全球 COVID-19 疫苗接种的推进，本病例强调了在扫描时记录疫苗接种史的重要性，以避免假阳性结果。
