COVID-19 感染症の無症候性症例における F-FDG PET/CT の結果を報告する。27歳の女性が，化学療法4サイクル目後のIIIE期B型ホジキンリンパ腫の再評価のためにFDG PET/CTを施行した．特に左肺に強烈なFDGの尿膜下混合地ガラスと集積性病変を認めた。このような形態代謝的側面と流行の背景から，ウイルス性肺炎が疑われた．当初無症状だった患者はPET/CT検査後28時間後に発熱で入院した。鼻咽頭スワブはCOVID-19陽性であり，予後は良好であった．

We report the results of F-FDG PET/CT in an asymptomatic case of COVID-19 infection. A 27-year-old woman underwent FDG PET/CT for revaluation of a stage IIIE B Hodgkin lymphoma after the fourth cycle of chemotherapy. It showed intense avid FDG subpleural mixed ground-glass and consolidative lesions, especially in the left lung. Because of this morpho-metabolic aspect and the epidemic context, a viral pneumopathy was suspected. The patient who was initially asymptomatic was admitted for fever 28 hours after the PET/CT. The nasopharyngeal swab was positive for COVID-19, and the outcome was favorable.
