摘要
目的:分析新型冠状病毒肺炎(COVID-19)的典型CT表现及临床特点,旨在提高其认识及影像诊断水平,改善患者预后,提高其治愈率。方法:回顾性收集2020年1月—2020年4月经临床取样咽拭子核酸检测证实为新型冠状病毒肺炎患者32例,总结分析其CT影像表现及临床特征。结果:在32例患者中,26例COVID-19患者核酸检测结果阳性,其中23例从武汉回来,3例有密切接触史;5例无症状感染者,1例疑似病例。临床表现为发热15例,持续性咳嗽12例,白细胞计数正常而淋巴细胞计数降低5例。CT表现为散在斑片影7例,大片实变影10例,其内见支气管充气征5例,磨玻璃样阴影5例,呈白肺样表现5例;病变分布左肺4例,右肺8例,两肺均有20例;以胸膜下分布为主22例,弥漫分布10例;伴有胸腔积液1例,伴有纵隔肿大淋巴结4例。在32例COVID-19患者中临床分型:轻型13例,普通型19例,无重型和危重型病例。结论:新型冠状病毒肺炎(COVID-19)具有典型的CT表现及临床特点,临床分型以轻型为主,具有明确的流行病学史,病变主要分布于肺外周胸膜下,较少并发胸腔积液及纵隔肿大淋巴结。
Objective:To analyze the typical CT manifestations and clinical features of novel coronavirus disease(COVID-19)in order to improve its understanding and imaging diagnosis level,improve the prognosis of patients and increase its cure rate.Methods:Thirty two patients with novel coronavirus confirmed by clinical sampling throat swab nucleic acid test from December 2019 to April 2020 were retrospectively collected,and their CT imaging manifestations and clinical characteristics were summarized and analyzed.Results:Of the 32 patients,26 patients with COVID-19 had positive nucleic acid test results,of which 23 returned from Wuhan and 3 had close contact history.Five asymptomatic infected persons and one suspected case.The clinical manifestations were fever in 15 cases,persistent cough in 12 cases,normal white blood cell count and decreased lymphocyte count in 5 cases.CT showed scattered patchy shadows in 7 cases,large solid shadows in 10 cases,bronchial inflation sign in 5 cases,ground glass shadows in 5 cases,and white lung-like manifestations in 5 cases.The lesions were distributed in 4 cases of left lung,8 cases of right lung and 20 cases of both lungs.Subpleural distribution was predominant in 22 cases and diffuse distribution in 10 cases.There was 1 case with pleural effusion and 4 cases with mediastinal enlarged lymph nodes.In 32 patients with COVID-19,the clinical classification included light 13 cases,common 19 cases,heavy and critical 0 case.Conclusion:Novel coronavirus(COVID-19)has typical CT manifestations and clinical features.The clinical classification is mainly light and has a clear epidemiological history.The lesions are mainly distributed under the peripheral pleura of the lung,with less pleural effusion and mediastinal enlarged lymph nodes.
