Table 3 - Association between CT chest signs and intensive care unit hospitalization, invasive endotracheal ventilation and death among positive RT-PCR COVID-19 patients. Dashes correspond to p > 0,05. ARDS, Acute Respiratory Distress Syndrom; CT, Computed Tomography; ICUH, Intensive Care Unit Hospitalization.
Figure 1. Flow-chart of the 349 patients suspected of COVID-19 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.
