Purpose The purpose of this study was to describe the clinical features and chest computedtomography (CT) findings of coronavirus disease 2019 (COVID-19) pneumonia.Materials and Methods An Institutional Review Board-approved retrospective review was performedfor 51 laboratory-confirmed COVID-19 pneumonia patients. Patients were divided intotwo groups depending on their clinical status: mild and severe. Clinical characteristics andchest CT findings were compared between the two groups.Results Among the 51 patients (22 men, 29 women; mean age, 56.5 ± 16 years; range, 22–88years), 37 (72.5%) were in the mild group and 14 (27.5%) were in the severe group. The patientsin the severe group (68.7 ± 12.5 years) were older than the patients in the mild group (51.8 ±14.9 years, p < 0.001). Premorbid conditions and decreased lymphocyte counts were more oftenobserved in the severe group than in the mild group (71% vs. 41%, p = 0.049 and 86% vs.32%, p = 0.001, respectively). On chest CT, most patients exhibited a mixed ground-glass opacification(GGO) with consolidation (76%) or a GGO (22%) pattern. The majority of lesions werepredominantly bilateral in the lower lung with a posterior, peripheral distribution. The patientsin the severe group had higher severity scores than those in the mild group.Conclusion Patients with laboratory-confirmed COVID-19 pneumonia have typical chest CTfindings that provide important information regarding expected disease severity.
