摘要
目的:分析新型冠状病毒肺炎(COVID-19)的CT表现与临床特点,提高对该病的认识。方法:回顾性分析41例临床诊断的COVID-19患者的临床及影像资料,男32例,女9例,平均年龄48.45岁。所有病例均经胸部CT检查,由两名高年资放射科医生对其影像学表现进行总结、分析。结果:COVID-19胸部CT主要表现为双肺磨玻璃样密度影、棉团状及网状小结节,双侧弥漫性分布,双下肺胸膜下为主,较双肺中上叶显著,右中叶受累相对少见。病程早期以肺外带、累及肺间质为主,多数病例可见细支气管充气征,可伴有粗大条索状影,胸膜下线。重症者随病程进展,病灶向支气管中轴间质蔓延,逐步扩散至全肺,可伴胸膜反应,叶间胸膜增厚、胸水少见。结论:COVID-19胸部CT表现具有一定特征性,结合临床流行性病学、临床症状、实验室检查可做早期临床诊断。
Objective:To analyze the clinical and CT features in patients with the corona virus disease 2019(COVID-19)to improve the understanding of the disease.Methods:The clinical and imaging data of 41 patients with COVID-19 were reviewed.There were 32 males(78%),9 were females(22%),with an average age of 48.45 years.All cases were examined by chest CT,and the imaging features were summarized and analyzed by 2 senior radiologists.Results:The chest CT of COVID-19 were mainly characterized by glass-like density,cotton clump like and reticular small nodules in both lungs,with bilateral diffuse distribution,and mainly in the subpleural area of the bilateral inferior lung fields,relatively rare in the right middle lobe.In the early stage of the disease,the peripheral lung field and the lung interstitial are involved,and air bronchogram can be seen in most cases,which can be accompanied by thick strands and subpleural lines.In severe cases,as the disease progresses,the lesion spreads to the main bronchial interstitial tissue and gradually spreads to the whole lung.It may be accompanied by pleural reactions,thickened interpleural pleura,and rare pleural effusion.Conclusion:Chest CT features of COVID-19 have certain characteristics,and early clinical diagnosis can be made by combining with clinical epidemiology,clinical symptoms and laboratory examination.
