新型冠状病毒肺炎早期胸部高分辨率CT表现

Chest high resolution CT manifestations of early stage corona virus disease 2019

目的观察新型冠状病毒肺炎(COVID-2019)早期胸部高分辨率CT(HRCT)表现。方法分析31例确诊COVID-2019患者早期胸部HRCT表现。结果31例发病1周内胸部HRCT呈不同程度肺炎改变。23例见多发病灶(≥3个病灶);24例病变累及2个以上肺叶,7例病灶累及单肺叶;22例表现为肺部磨玻璃密度病灶(GGO),9例GGO伴混合性实变灶,病灶边界均模糊;25例病变分布于肺外周带,6例病灶分布于肺外周伴局部中央分布;26例病灶呈不规则斑片状,5例呈不规则斑片状伴局部球形表现;26例伴细支气管充气征,29例病变内血管增粗,24例见小叶内间隔增厚,6例伴小叶间隔增厚;2例伴小叶中心结节,1例伴少量胸腔积液。结论COVID-2019早期胸部HRCT表现具有一定特征性,结合临床病史有利于早期诊断COVID-2019。

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.
