Resumen:
Background: From the first report of the respiratory disease caused by
SARS-Cov-2 towards the end of 2019, in Wuhan, China, to June 8, 2020,
6,931,000 people had been affected in the world, and 113,619 in Mexico,
where there is a lack of literature describing the tomographic behavior
of this disease throughout its evolution and its correlation with
patient clinical data. Objective: To identify, describe and classify the
manifestations detected on chest computed tomography images of patients
with pneumonia caused by SARS-CoV-2. Method: Hospitalized patients with
RT-PCR-confirmed SARS-CoV-2 infection and who underwent a plain chest
tomography were included. Results: The most common tomographic patterns
were ground glass opacity, consolidation, cobblestone pattern and mixed
pattern, with peripheral and subpleural distribution and bilateral
involvement in up to 95 %. Subpleural bands that distorted the
architecture were identified in up to 62 % of patients, with an average
of seven days of evolution. The most common extrapulmonary finding was
an increase in pulmonary artery transverse axis. Conclusion: Knowing the
behavior of this type of pneumonia allows becoming familiarized with the
characteristic tomographic patterns, in order to aid timely detection
and treatment.
