Summary: | Purpose The purpose of this study was to describe the clinical features and chest computed
tomography (CT) findings of coronavirus disease 2019 (COVID-19) pneumonia.
Materials and Methods An Institutional Review Board-approved retrospective review was performed
for 51 laboratory-confirmed COVID-19 pneumonia patients. Patients were divided into
two groups depending on their clinical status: mild and severe. Clinical characteristics and
chest CT findings were compared between the two groups.
Results Among the 51 patients (22 men, 29 women; mean age, 56.5 ± 16 years; range, 22–88
years), 37 (72.5%) were in the mild group and 14 (27.5%) were in the severe group. The patients
in 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 often
observed 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 were
predominantly bilateral in the lower lung with a posterior, peripheral distribution. The patients
in the severe group had higher severity scores than those in the mild group.
Conclusion Patients with laboratory-confirmed COVID-19 pneumonia have typical chest CT
findings that provide important information regarding expected disease severity. |
