unit hospitalization, invasive endotracheal ventilation and death among
positive RT-PCR COVID-19 patients. Dashes correspond to p >

infection included in the study.
Figure 2. Main chest CT signs in the 109 COVID-19 positive
RT-PCR cases according to the delay between first symptoms and the first
chest CT. CT, Computed Tomography; RT-PCR, Real Time
Reverse-Transcription Polymerase Chain Reaction.
Figure 3. Chest CT in positive RT-PCR COVID-19 cases - (a) A 74
years old man in ICU with endotracheal ventilation, 11 days after first
symptoms, massive bronchial distortion (white arrow) in all the right
lung, large areas of ground glass opacities and subpleural
consolidation, with ≥ 75 % of total lung involvement. Note a left
anterior loculated pneumothorax and a left posterior pleural effusion
drain. (b) A 57 years old man in ICU, 13 days after first symptoms, dual
distribution areas (subpleural and central) of ground glass opacities in
the lingula and the right inferior lobe with bronchial distortion (black
arrow) and vascular dilatation (white arrow), with 50-75 % of total
lung involvement. (c) A 67 years old man in ICU, 10 days after first
symptoms, CT aspect of organized pneumonia (white arrow) with bilateral
posterior subpleural curvilinear bands. CT, Computed Tomography; ICU,
Intensive Care Unit; RT-PCR, Real Time Reverse-Transcription Polymerase
Chain Reaction.
Figure 4. Chest CT of a 76 years old man in ICU, showed 10 days
after first symptoms, bilateral, large and patchy ground glass opacities
with crazy paving (white underlined dark arrow), bronchial distortion
(white arrow) and vascular dilatation (dark arrow), with 50-75 % of
total lung involvement. CT, Computed Tomography; ICU, Intensive Care
Unit.
