Figure 1. (1–7) CT scans during hospital stay. Chest CT scans (Contrast spiral-CT; axial [above] and coronal [below] plane) on admission showed bilateral infiltrates, predominant basal distribution, and development of fibrosing alveolitis in all patients (yellow arrows). Patients 5 (and 6) received a second CT scan (52/62) on day 11 (and 8), showing peripheral lung consolidation interpreted as bacterial superinfection by our local radiologist.
