Abstract:
Forty-one patients with COVID-19 (22 males and 19 females with the age of 24~94 years) from February to March 2020 were enrolled in the study, including 15 severe or critically ill cases (severe group) and 26 moderate cases (non-severe group). The CT findings of intrapulmonary lesions at admission were evaluated and compared between severe and non-severe groups. There were significant difference between severe and non-severe groups in the aspects of the presence or absence of pure ground-glass opacity (GGO) (χ 2=10.791), GGO with focal consolidation (χ 2=5.512), sheet consolidation (χ 2=27.359), crazy paving sign (χ 2=8.343), thickening of the bronchial wall (χ 2=14.473), air bronchogram sign (χ 2=4.977), and pleural effusion (χ 2=6.561), all P<0.05. Multivariate logistic regression analysis showed that range of lesion involvement was a relevant factor for severe cases( OR=0.029,95 %CI:0.001-0.647, P=0.026). The study indicates that CT features are diverse in COVID-19 patients; there is lack of pure GGO, but more GGO with focal consolidation. The appearance of sheet consolidation and crazy paving sign and wide-range of lesion involvement and pleural effusion in CT findings may be indications for severe COVID-19.
