An 87-year-old man with primary salivary duct carcinoma and hepatic metastases was referred for restaging. F-FDG PET/CT demonstrated new FDG-avid ground-glass opacities with intralobular septal thickening in both lungs with a peripheral dominant distribution. This was interpreted as a pattern highly suggestive of COVID-19 pneumonia, and the referring physician was contacted. The patient was currently asymptomatic and without clinical evidence of active pneumonia. However, the patient tested positive for COVID-19 using real-time reverse transcription-polymerase chain reaction. This case demonstrates that even asymptomatic outpatients undergoing PET/CT should be evaluated for radiologic findings suggestive of COVID-19 during this pandemic.
一位 87 岁男性，原发性涎腺导管癌伴肝转移，为了重新分期来诊。18F-FDG PET/CT 显示双肺新出现 FDG 摄取的磨玻璃样混浊，伴有小叶间隔增厚，呈外周优势分布。这高度提示为 COVID-19 肺炎，联系了转诊医生。患者目前无症状，无活动性肺炎的临床证据。然而，实时逆转录-聚合酶链反应检测 COVID-19 阳性。本病例表明，即使是在大流行期间进行 PET/CT 的无症状门诊患者，也应评估提示 COVID-19 的影像学发现。
