Evolution of computed tomography manifestations of eleven patients with severe coronavirus disease 2019 (COVID-19) pneumonia.

ABSTRACT

PURPOSE: Severe coronavirus disease 2019 (COVID-19) pneumonia is associated with high mortality. However, the evolution of computed tomography (CT) manifestations of severe COVID-19 pneumonia remains unclear, more evidence regarding its evolution process is urgently needed. METHOD: The clinical, laboratory and imaging data of eleven patients with severe COVID-19 pneumonia were collected to investigate the evolution process of severe COVID-19 cases. RESULTS: The main initial CT manifestations of severe COVID-19 pneumonia were multiple ground-glass opacities and/or consolidation. The evolution of CT manifestations showed that acute exudative lesions of severe COVID-19 pneumonia could be gradually resolved after the active intervention. CONCLUSIONS: Most of patients with severe COVID-19 pneumonia showed marked improvement of acute exudative lesions on chest imagings and satisfactory prognosis of severe COVID-19 pneumonia could be achieved after active treatment.
