疑似及确诊新冠肺炎的临床及胸部CT影像特点

Clinical and Chest CT Features of Suspected and Confirmed NovelCoronary Pneumonia

目的分析我院收治的疑似及确诊的新型冠状病毒肺炎患者的临床及胸部CT影像表现,以提高对本病的认识。方法选择我院2020年1月15日~2月15日收治的26例疑似和确诊新型冠状病毒肺炎患者的作为研究对象,回顾性分析患者流行病学史、临床资料、实验室检查及胸部CT影像学表现。结果26例患者中,16例为确诊病例,10例为疑似病例。15例患者疫情期间曾经到过武汉或生活在武汉,4例患者有家属来自武汉,1例患者来自湖北荆州,1例患者有新加坡旅游史,2例患者接触过确诊病例,3例患者没有明确接触史。发热患者21例,无症状患者4例,1例仅有少许咳嗽。26例患者胸部CT主要表现为肺内散在分布的斑片状、结节状、大片状磨玻璃影、实变影,大部分位于胸膜下,其中18例患者胸部影像表现为病毒性肺炎可能性大。结论结合流行病学史、临床症状、实验室检查及胸部CT影像学资料可以准确诊断及鉴别新型冠状病毒肺炎,达到早发现、早隔离、早治疗的目的。

Objective To analyze the clinical and chest CT imaging findings of patients with suspected and confirmed novel coronavirus pneumonia admitted in our hospital to improve the understanding of the disease.Methods 26 patients with suspected and confirmed novel coronavirus pneumonia treated in our hospital from January 15 to February 15,2020 were selected as the research subjects,retrospective analysis of the patient's epidemiological history,clinical data,laboratory tests and chest CT imaging findings.Results Of the 26 patients,16 were confirmed and 10 were suspected.15 patients had visited or lived in Wuhan during the epidemic,4 patients had family members from Wuhan,1 patient from Jingzhou,Hubei,1 patient had a history of travel in Singapore,2 patients had contact with a confirmed case,and 3 patients were unclear contact history.There were 21 cases of fever,4 cases of asymptomatic patients,and 1 case had only a little cough.Chest CT in 26 patients mainly showed patchy,nodular,large ground glass,and consolidation in the lungs.Most of them were located under the pleura.18 of these patients were most likely to have viral pneumonia.Conclusion Combining epidemiological history,clinical symptoms,laboratory examination and chest CT imaging data can accurately diagnose and identify novel coronavirus pneumonia,and achieve the goals of early detection,early isolation and early treatment.
