摘要
目的:分析老年新型冠状病毒肺炎(COVID-19)患者的CT表现,为临床诊断提供影像学依据。方法:对武汉大学中南医院收治的36例新型冠状病毒核酸阳性的老年患者临床资料和胸部CT影像资料进行回顾性分析。结果:老年COVID-19患者合并基础疾病较多,临床症状比年轻人复杂,常有发热(77.8%)、咳嗽(55.6%)、呼吸困难(52.8%)等;CT征象具有多样性、多灶性的特点,主要表现为肺内磨玻璃影与实变影共存(72.2%),多位于双侧肺中外带肺野(69.4%),病灶内可见空气支气管征(58.3%),病情进展相对较快,重症肺炎者居多,男性患者稍多(55.6%)。结论:老年COVID-19患者的CT影像有一定的特征性,胸部薄层CT有助于早期诊断,是对核酸检测的有效补充。
Objective:CT findings of 36 elderly patients with novel corona virus disease 2019(COVID-19)were analyzed to provide imaging diagnostic basis for clinical diagnosis.Methods:The clinical date and chest CT images of 36 elderly patients with positive new coronavirus nucleic acid admitted to Zhongnan Hospital of Wuhan University were retrospectively analyzed.Results:Elderly COVID-19 patients had more underlying diseases,with more complicated clinical symptoms than young patients,including fever(77.8%),cough(55.6%),and dyspnea(52.8%);CT signs are characterized by diversity and multi-focus,mainly showing the coexistence of ground-glass shadow and consolidation shad-ow(72.2%),mostly located in the outer lung field of bilateral lung(69.4%),and the air bronchus sign(58.3%)in the lesions.COVID-19 in the elderly progresses relatively fast,and severe patients were more common,and 55.6%patients were male.Conclusion:CT images of elderly COVID-19 patients have certain characteristics.Chest thin-section CT is helpful for early diagnosis and provides an effective supplement to nucleic acid detection for SARS-CoV-2.
