Abstract
in English, French

Since the beginning of 2020, coronavirus disease 2019 (COVID-19) has spread throughout China. This study explains the findings from lung computed tomography images of some patients with COVID-19 treated in this medical institution and discusses the difference between COVID-19 and other lung diseases.

Depuis le début de l’année 2020, la maladie à coronavirus 2019 (COVID-19) s’est répandue dans toute la Chine. Cette étude analyse les résultats tirés des images de TDM pulmonaire de certains patients atteints de COVID-19 traités dans cet établissement médical et examine la différence entre le COVID-19 et d’autres maladies pulmonaires.

Keywords: 2019n-CoV; COVID19; CT; lung diseases; pneumonia.

A 52-year-old male: Computed tomography scan revealed patchy pure ground-glass opacities (red arrow) at the lateral basal segment of the right lower lobe and vascular dilation inside the lesion.

A 63-year-old male: High-resolution computed tomography scan showed multiple pure ground-glass opacities in the right lower lobe, a distribution of lesions in the subpleural area and lung periphery, a “crazy-paving” pattern, and interlobular septal thickening (red arrow).

A 48-year-old male: High-resolution computed tomography scan showed multiple ground-glass opacities in multiple lobes of both lungs, interlobular septal thickening, and a crazy-paving pattern (red arrow).

A 47-year-old male: High-resolution computed tomography scan showed patchy consolidations on the left upper lobe, partially consolidated lung tissue, ground-glass opacities on the edge, and air bronchograms in the lesion (red arrow).

Figure 5.
A 60-year-old female: High-resolution chest computed tomography scan revealed extensive patchy exudates and consolidation of both lungs, faint ground-glass opacities on the edge, and interlobular septal thickening (red arrow).

A 58-year-old female: High-resolution chest CT showed extensive GGOs in both lungs, which were mainly distributed along the hila, interlobular septal thickening, and interlobar pleural thickening (red arrow).
