3月26日から4月6日の間に、当科（イタリア・ブレシア）でF-FDG PET/CTを受けた80名の患者のうち、4名にCOVID-19を疑う間質性肺炎が認められ、逆転写酵素ポリメラーゼ連鎖反応で確認された。1例を除くすべての患者は、少なくとも2つの肺葉に両側性の基底硝子体混濁および/または肺凝固を認めた。下肺葉と基底部分節が最も頻度の高い病変部位であった。すべての肺病変で間質性肺炎に対応するFDG上昇が認められ，1例では縦隔結節の病変が認められた．

Between March 26 and April 6, among 80 patients who underwent F-FDG PET/CT in our department (Brescia, Italy), 4 showed the presence of an interstitial pneumonia suspected for COVID-19 with reverse transcriptase polymerase chain reaction confirmation. All patients except one had bilateral ground-glass opacities and/or lung consolidations in at least 2 pulmonary lobes. Inferior lobes and basal segments were the most frequent site of disease. All lung lesions had an increased FDG uptake corresponding to the interstitial pneumonia, and in one case, mediastinal nodal involvement was registered.
