Abstract

Objective: To explore high chest resolution CT (HRCT) manifestations of early stage corona virus disease 2019 (COVID-2019). Methods: Chest HRCT findings of 31 COVID-2019 patients were retrospectively analyzed. Results: Chest HRCT showed vary degrees changes of pneumonia within 1 week of onset. Multiple lesions (3 or more lesions) were found in 23 cases. Lesions affected 2 and more pulmonary lobes were observed in 24 cases, while single pulmonary lobe involvement was observed in 7 cases. Multiple ground-glass opacity (GGO) was noticed in 22 patients, while in other 9 cases multiple GGO mixed consolidation were found, all had fuzzy boundaries. The lesions presented at peripheral lungs in 25 cases, while in 6 cases presented at peripheral combined and central lungs. Lesions of irregular morphology were observed in 26 cases, while rounded morphology and sphericity were observed in the other 5 cases. Air bronchogram was noticed in 26 cases, thickening vascular in the lesions were found in 29 case, thickened intralobular interstitium in 24 cases, thickened interlobular interstitium in 6 cases, centrilobular nodules in 2 cases and a small amount of pleural effusion in 1 case. Conclusion: The early chest HRCT manifestations of COVID-2019 have certain characteristics. Combination of clinical history and chest HRCT manifestations is conducive to early diagnosis COVID-2019.

冠状病毒病早期胸部高分辨率CT表现

目的:探讨2019冠状病毒病(COVID-2019)早期高胸部分辨率CT (HRCT)表现。方法:回顾性分析31例新冠肺炎患者胸部HRCT表现。结果:发病1周内胸部HRCT显示不同程度的肺炎改变。多发病灶(3个及以上)23例。病变累及2个及以上肺叶24例，累及单肺叶7例。22例可见多发磨玻璃样混浊(GGO)， 9例可见多发磨玻璃样混浊，边界模糊。病变表现为外周肺25例，外周合并肺和中央肺6例。26例病变形态不规则，5例病变形态圆润、球状。支气管充气征26例，病变血管增厚29例，小叶间质增厚24例，小叶间质增厚6例，小叶中心结节2例，少量胸腔积液1例。结论:2019冠状病毒病早期胸部HRCT表现具有一定特点。结合临床病史和胸部HRCT表现有利于早期诊断。
