Abstract
Objective: To analyze the characteristics, dynamic changes, and outcomes of the first imaging manifestations of 3 patients with severe COVID-19 in our hospital. Methods: Computed tomography (CT) findings of 3 patients with severe COVID-19 who tested positive by the nucleic acid test in our hospital were selected, mainly focusing on the morphology, distribution characteristics, and dynamic changes of the first CT findings. Results: 3 patients with severe pneumonia were older, with one aged 80. The first chest CT examination for all 3 patients differed. Imaging showed a leafy distribution of consolidation, primarily affecting the lower lobes of both lungs and extending subpleurally. A grid-like pattern was observed, along with changes in the consolidation and air bronchogram. These changes had slower absorption, especially in patients with underlying diseases. Conclusion: CT manifestations of severe COVID-19 have specific characteristics and the analysis of their characteristics and dynamic changes provide valuable insights for clinical treatment.
