A 59-year-old woman with Covid-19. Same level of mid-axial (A, C and E) and mid-coronal (B, D and F) chest CT scans on admission (A–B), on the day of tocilizumab given because of requirement of oxygen support and progressive lung imaging (C–D) and 7 days after onset of tocilizumab (E–F), retrospectively.

A–B: Focal peripheral ground-glass opacities. The left upper lobe lesions were accompanied by consolidation with bronchiectasis.

C–D: Chest CT showed that the lesions had become larger with some peripheral newer small consolidation.

E–F: The lesions were suppressed and improved.
