Abstract :Backround: The aim of this study is to report the clinical course of the disease and the correlation of thorax computed tomography insert ignore into journalissuearticles values(CT); feaures in patients with clinically suspected and laboratory confirmed COVID-19 pneumonia by reviewing the limited datas of literatüre. Materials and Methods: Totally 104 patients insert ignore into journalissuearticles values(39 females and 65 males; age range, 22-91 years); admitted to our hospital with suspicion of COVID-19 pneumonia were retrospectively reviewed for common thorax CT features, laboratory findings and clinical manifestations.. All patients were positive in reverse transcriptase polymerase chain reaction test insert ignore into journalissuearticles values(RT-PCR); indicating Covid 19 pnemonia and all had abnormal CT findings. The main clinical signs, common laboratory findings and expressing the stages of the disease by CT findings were examined. Results: 18 insert ignore into journalissuearticles values(17.3%); of the 104 patients with Covid 19 were as single, the remaining 86 insert ignore into journalissuearticles values(82.7%); were as multiple lesions on initial CT scans. The spread of these lesions were predominantly peripheral in 80 patients insert ignore into journalissuearticles values(76.9%); and peripheral-central in 24 patients insert ignore into journalissuearticles values(23.1%);. In the early stage of the disease,lesions identified as ground glass opacites insert ignore into journalissuearticles values(GGO); whereas in the advanced stages, GGO and reticular pattern, air bubbles, subpleural fibrotic bands, air bronchograms, traction bronchiectasis and pleural effusion were observed. 52 patients who underwent routine blood tests, all insert ignore into journalissuearticles values(%100); had elevated C reactive protein insert ignore into journalissuearticles values(CRP); counts. 11patients insert ignore into journalissuearticles values(21.1%); had decreased leukocyte count. 48 patients insert ignore into journalissuearticles values(92.3%); had decreased lymphocyte count. 14 patients insert ignore into journalissuearticles values(28%); had increased d-dimer levels. Conclusions: Various lesions were detected in the CT examine like parenchyma and/or interstitium involvement of patients with Covid 19 pneumonia. In early stages, parenchymal involvement were more frequent identified as a single or multiple GGO. Multilobar involvement, consolidation areas with air bubbles and bronchograms, widespread GGO and reticular pattern which is called crazy pavings were much more detected in the late stage of the disease. Prominent decrease in the lymphocyte count,and higher C-reactive protein levels were the most frequent laboratory findings.
