The evolution of lung computed tomography findings in COVID-19 from 2020 to 2023: more signs of co-infection

Abstract

Significant changes were observed in the lung imaging of hospitalised COVID-19 patients from 2020 to 2023, with the emergence of more signs of co-infection https://bit.ly/3TaQlJ2.

FIGURE 1

Evolution of radiological findings of patients hospitalised with coronavirus disease 2019 (COVID-19) from 2020 to 2023. a) Changes in the proportion of immunocompromised patients hospitalised with COVID-19 (n=878) over time since the start of the pandemic; b) changes in chest computed tomography (CT) scan interpretation by radiologist (proportion of patients with typical signs of COVID-19, and with signs of bacterial co-infection); c) chest CT scan finding of a 66-year-old female patient with overweight and hypertension who presented in April 2020 with severe COVID-19 requiring mechanical ventilation. Chest CT scan showed bilateral ground-glass opacities characteristic of COVID-19 with no signs of co-infection; d) 46-year-old female patient with kidney transplant under antirejection immunosuppressive therapy who presented in December 2022 with fever, respiratory signs and hypoxaemia. A COVID-19 infection was diagnosed; chest CT scan showed no signs of COVID-19 pneumonia, but a left inferior lobar consolidation evocative of co-infection. Jan: January; Dec: December.
