Chest computed tomography (CT) is one of the main tools in the diagnostic approach.Methods: we conducted a retrospective study of Covid-19 cases confirmed and hospitalized during the period between October, 2020 and December, 2020. All the patients had a CT chest exploration.Results: One hundred patients were included in the study. The sex-ratio was 1.7 (63 men and 37 women). The mean age was 62 years. The viral pneumonia was classified moderate to severe in 63\% of cases. The different radiological lesions were located in the sub pleural and lower regions in 70\% of cases. The damage was unilateral in 25 patients, which is often associated with a mild form. Ninety eight percent of patients presented frosted glass images predominating in the lower lobes, the crazy paving aspect were present in only 39\% with septa thickening in 22\%. Ten patients had pulmonary fibrosis associated with an incidental discovery. Fifty three percent of patients had lesions of diffuse emphysema, which was correlated to tobacco intoxication. Only 25\% of patients with severe pneumonia had extensive lesions on chest CT estimated more than 75\%.Measurements and Main Results: The place of the chest CT in the positive diagnosis of Covid-19 is indisputable. Radiological presentation is not always typical. The linkages between the severity of pneumonia and CT findings should be more studied.FootnotesCite this article as: European Respiratory Journal 2021; 58: Suppl. 65, PA3236.This abstract was presented at the 2021 ERS International Congress, in session {\textquotedblleft}Prediction of exacerbations in patients with COPD{\textquotedblright}.This is an ERS International Congress abstract.
