Fig. 1. Radiologic courses of 56-year-old patient with COVID-19.
56-year-old man who had cough, myalgia, and chillness for week was diagnosed with COVID-19 three days before admission. A. He abruptly complained of hemoptysis and dyspnea, and chest radiograph showed bilateral consolidations and GGOs in both middle and left lower lung field. B–D. On day 2 and 3, chest radiographs and CT showed rapid progression of bilateral consolidations. COVID-19 = coronavirus disease 2019, GGO = ground-glass opacity

Darkly colored means that degree is severe. Low-grade fever, 37.5–38.2℃; high-grade fever, > 38.3℃; C-reactive protein elevation was divided into < 10, 10–19.9, 20–29.9, ≥ 30 mg/dL; lopinavir/ritonavir and hydroxychloroquine were used as treatment; haziness of chest radiograph was divided into < 10%, 10–49%, 50–69%, ≥ 70% of total lung involvement. ARDS = acute respiratory distress syndrome, ICU = intensive-care unit, PCR = polymerase chain reaction, ROX index = respiratory rate-oxygenation index (calculated as ratio of oxygen saturation/fraction of inspired oxygen)
