Imaging related to underlying immunological and pathological processes in COVID-19

Figure 11  Axial computed tomography images. Axial computed tomography images on day 2 (A) and day 10 (B) from onset of symptoms of patient with clinical worsening demonstrate increased ground-glass opacities with confluence, crazy-paving appearance and typical peripheral subpleural location, early (A) and progressive (B) stage. Axial images from CT on day 5 (C) and day 15 (D) from onset of symptoms of patient with pronounced clinical worsening demonstrate increased ground-glass opacities with confluence, crazy-paving appearance and extensive areas of consolidation (red arrows) with predominant posterior and lateral distribution. In addition, bilateral pleural effusions (black arrows) are noted, early (C) and peak (D) stage.
