Abstract

Objective: The purpose of this study was to describe the characteristics and progression of lung lesions on chest X-ray and CT scans in COVID-19 patients with pneumonia treated at National Hospital of Tropical Diseases. Materials and methodes: Design of a cross-sectional descriptive study performed  in 200 patients with COVID-19 who were treated at National Hospital of Tropical Diseases from January 2020 to May 2021. Results: 91.5% of patients had no lesions on chest X-ray, while lung lesions detected on chest CT were 53% of patients.Characteristics of lung lesions on chest X-ray: 64.7% of patients had lesions in 2 lungs, 41.2% had lesions in the lower third, and 35.3% had diffuse lesions. The lesion morphology included: opacities (70.6%), interstitial thickening (17.6%), frosted glass (11.8%).Characteristics of lesions on chest CT: lesions are mainly located in the periphery of the lung (57.5%), both central and peripheral (38.7%). Distribution of lesions in multiple lobes of 2 lungs (68%). The most common lesions are: frosted glass (91.5%), solidified (22.6%), interstitial thickening (14.2%). Progression of lesions on chest CT: after 15 days of treatment, 68% of patients' lesions tend to decrease or return to normal, 2.8% of patients tend to remain unchanged, 6.6% of patients aggravated, the lesion tends to worsen.
