On admission, the patient presented with fever but without dyspnea. A chest CT showed bilateral scattered ground-glass opacities. On Day 4, although the patient still denied dyspnea, a chest CT showed progressive bilateral ground-glass opacities. On Day 8, the patient experienced a rapid decline of the P/F ratio, and a chest CT showed bilateral heterogeneous diffusive ground-glass opacities with consolidation in dorsal areas, much worse than previously, leading to intubation and then ECMO. After the patient had been weaned from ECMO, chest CT exams on Day 57 and Day 75 showed significant resolution of the consolidation and ground-glass opacities, which corresponded to a de-escalation of respiratory support. After being discharged from hospital, the patient had chest CT scanned 2 weeks after discharge, 1 month after discharge, and 1 year after discharge, respectively. These images revealed further resolution of former opacities.

A chest CT indicated bilateral scattered mottled ground glass shadows in the lungs (Table 1; Figure 1). On May 14, one month after his discharge, his mMRC dyspnea scale score improved to grade 1, and a CT scan showed further absorption of lung lesions (Figure 1).
