Introduction:

The new coronavirus (2019-nCoV) can cause a mild, moderate or severe respiratory infection, even death.

Objectives:

To determine the complication-inducing tomographic (CT) criteria in patients with 2019-nCoV pneumonia.

Materials and methods:

An observational, analytical case-control study of 123 patients with 2019-nCoV pneumonia who underwent a chest CT scan. The data are expressed in means and proportions. Odds Ratio, Cramer's coefficient, chi-square test and Student's “t” were calculated for the comparison of groups, considering p <0.05 as significant.

Results:

Age range from 23 to 87 (57.1 ± 13.9) years. 70 (56.9%) were male. The infiltrate of the pulmonary parenchyma en bloc was found in 38 (30.9%), in 80 (55%) ground glass and in 5 (4.1%) pseudo nodular. In 54 (43.9%) it was diffuse, bilateral in 80 (65%), and parietal thickening in 55 (44.7%). Pleural effusion in 15 (12.2%), cardiomegaly in 11 (8.9%), and both in 15 (12.2%) and none in 82 (66.7%). The type of infiltrate (p = 0.000 R2 = 0.79), the type of distribution (p = 0.038 R2 = 0.69), the wall thickening (p = 0.000 R2 = 0.71) were significant.

Conclusion:

Chest CT shows images that suggest an evolution to some type of complication in patients with 2019-nCoV pneumonia.
