新型冠状病毒肺炎临床与胸部CT表现

Novel Coronavirus Pneumonia:Clinical and Chest CT Findings

目的:分析2019新型冠状病毒肺炎(COVID-19)胸部CT表现,为早期发现、诊断、隔离及治疗提供参考.方法:回顾性分析我院8例确诊COVID-19患者临床资料和胸部CT影像表现,重点观察CT病灶的密度、大小、形态、数目及分布情况.结果:8例患者均可见磨玻璃影(部分可见亚实性磨玻璃影)、其形态不一,数目较多,以双肺外周及下叶分布为主,并见小血管影增粗(n=8)、细网格影(铺路石征)(n=6)、支气管充气征(n=5)、支气管壁增厚(n=4)、条索影(n=3)等伴随征象.2例合并双肺下叶实变影,1例患者见微小结节,周围可见晕征.8例患者均未见胸腔积液及纵隔淋巴结肿大.结论:COVID-19胸部CT表现有一定特征性,胸部CT检查对患者的早期筛查起着重要作用.

Objective:To analyze the chest CT manifestations of 2019 novel coronavirus pneumonia(COVID-19),and to provide reference for early detection,diagnosis,isolation and treatment.Methods:The clinical data and chest CT findings of 8 patients with COVID-19 were analyzed retrospectively.The focused observations were on the density,size,shape,number and distribution of CT lesions.Results:The ground glass and partial ground glass shadow was found in 8 cases,which was mainly distributed in the lower lobes and peripheral areas of both lungs,which was accompanied by small vessel shadow thickening(n=8),fine mesh shadow(paving stone sign)(n=6),bronchi inflation sign(n=5),bronchi wall thickening(n=4),strip shadow(n=3).Two cases had consolidation of lower lobe of both lungs.In one patient,there was a small nodule and halo sign around.There was no pleural effusion or lymphadenopathy in 8 patients.Conclusion:CT findings of COVID-19 have certain characteristics.Chest CT plays an important role in early screening of patients.
