PET (left panel), CT (middle), and PET/CT (right). First row: upper lung. Second row: middle lung. Third roe: lower lung. The patient underwent examination within his routine follow-up for a prostate adenocarcinoma. PSA was 1.97 ng/ml and unchanged compared with the previous evaluation. The CT scan shows diffuse wide areas of solid-subsolid ground-glass opacities, bilateral and subpleural crazy-paving bronchovascular thickening. The patient referred mild fever (>38 °C), cough, fatigue, shortness of breath, ageusia-dysgeusia and anosmia, all strongly suggestive symptoms for a Covid-19 infection. PET shows some mild-intense areas of uptake which follow, with irregular shape and intensity, the CT alterations.
