Chest CT images of an 83-year-old male patient (case 20, COVID-19 PCR-positive, hospitalised) with SARS-CoV-2 that developed during hospitalisation for thoracic empyema. CT shows non-segmental sub-pleural ground-glass opacity with consolidation (white arrow), which is compatible with COVID-19 pneumonia in the right lower lobe. Left thoracic empyema accompanied by atelectasis in the left lower lobe is evident (white arrowhead). Note that the left lower lobe lacks findings compatible with COVID-19 pneumonia (RSNA category: indeterminate appearance).
