Initial Screening Chest Computed Tomography Findings of Patients Who Were Admitted to Fırat University Hospital with Pre-diagnosis of Coronavirus Disease 2019 (COVID-19)
Abstract
Objective: To evaluate radiological findings on initial screening of the patients who had chest computed tomography (CT) with the pre-diagnosis of coronavirus disease-2019 (COVID-19).
Material and Methods: Chest CT images of 90 patients with a pre-diagnosis of COVID-19 were retrospectively analyzed. Demographic characteristics, symptoms, and comorbid conditions of the patients were recorded. The chest CT findings on initial screening and follow-up were analyzed.
Results: The chest CT findings on the initial screening of the patients with a pre-diagnosis of COVID-19 included ground-glass opacities (GGOs) (59%), consolidation (34%), crazy-paving pattern (5%), air bronchogram (18%), vascular dilation (6%), bronchiectasis-bronchial wall thickening (7%), air bubble (7%), subpleural line (10%), halo sign (5%), nodule with irregular borders (9%) and reverse halo sign (%4). The predominant findings in the follow-up CT images included newly developing consolidations in the progression stage, GGOs converting to consolidations, bilateral pleural effusion, traction bronchiectasis, and hilar lymphadenopathy. In the regressed cases, it was observed that the consolidation we observed in the first CT imaging turned into GGOs.
Conclusion: Ground-glass opacities were the most common finding in initial screening thorax CT scans of patients with pre-diagnosis of COVID-19. An increase in the ground-glass densities or consolidation areas identified upon initial examination, bilateral pleural effusion, traction bronchiectasis, and hilar lymphadenopathies were observed in the progression stage
