背景：关于冠状病毒病（COVID-19）无症状患者的呼吸系统损害知之甚少。目的：在此，我们评估了无症状COVID-19患者的胸部计算机断层扫描（CT）和X线检查结果。方法：我们回顾性调查了确诊为COVID-19但没有表现出任何症状的患者。在韩国大邱的岭南大学医院住院的139名COVID-19患者中，有10名（7.2%）无症状。分析其胸部CT和X线表现。结果：本组病例胸部CT均表现为磨玻璃样阴影（GGO），阳性率为100%。此外，在所有患者中，GGO病变主要分布在外周和后方。9例（90%）GGO病变合并网状阴影。8例（80%）可见GGO包绕的细支气管扩张所致支气管充气征。此外，所有患者的肺部病变均以右侧为主。结论：综上所述，考虑到我们的结果，即无症状患者的肺部受到影响，有必要扩大COVID-19检测的适应症，以在大流行期间有效管理COVID-19。
Background: Little is known about the damage to the respiratory system in asymptomatic patients with coronavirus disease (COVID-19). Objective: Herein, we evaluate the findings of chest computed tomography (CT) and radiography in patients with COVID-19 who were asymptomatic. Methods: We retrospectively investigated patients with a confirmed diagnosis of COVID-19 but who did not show any symptoms. Among the 139 patients with COVID-19 who were hospitalized in Yeungnam University Hopistal in Daegu, South Korea, 10 (7.2%) were asymptomatic. Their chest CT and radiographic findings were analyzed. Results: In the results, all patients (100%) had ground-glass opacity (GGO) on chest CT. Further, the GGO lesions were predominantly distributed peripherally and posteriorly in all patients. In 9 (90%) patients, the GGO lesions were combined with reticular opacity. Air bronchogram due to bronchiolectasis surrounded by GGO was observed in 8 patients (80%). Additionally, the lung lesions were dominant on the right side in all patients. Conclusions: In conclusion, considering our results that the lung is affected in asymptomatic patients, it will be necessary to extend the indications of COVID-19 testing for effective management of COVID-19 during the pandemic.
