Chest CT images of a 65-year-old female patient (case 16, COVID-19 PCR-positive, hospitalised, 12 days after onset) SARS-CoV-2 that developed during hospitalisation for a femoral neck fracture with comorbidity of intracranial haemorrhage (ICH) and heart failure as comorbidities. CT shows extensive consolidation and ground-glass opacities along with the bronchovascular bundles in both lungs, which is difficult to distinguish from acute respiratory distress syndrome (ARDS) (RSNA category: indeterminate appearance). In this case, methicillin-resistant Staphylococcus aureus (MRSA) was detected in the sputum collected 6 days before chest CT. Concomitant pneumonia caused by MRSA was suspected.
