摘　　要：目的探讨境内及境外输入性新型冠状病毒肺炎(COVID-19)确诊患者的首次胸部高分辨率CT(HRCT)影像表现及其临床特点。方法回顾性收集384例COVID-19确诊患者首次胸部HRCT的影像及临床资料,其中境内组270例(广州地区以外的境内输入性病例及其直接关联病例),境外组114例(发病前14 d内有明确国外旅居史的境外输入性病例及其直接关联病例),比较分析两组患者的影像及临床资料。结果境内组患者年龄5~90岁,平均(48.62±16.25)岁,男124例,女146例;境外组患者年龄16~63岁,平均(33.45±12.33)岁,男68例,女46例。临床症状多为发热、咳嗽;肺内未见病灶(轻型)境内组比例显著低于境外组;多发病灶比例境内组显著高于境外组,境内组累及2个及以上肺叶比例显著高于境外组,境内组各叶病灶发生比例均显著高于境外组;境内组出现磨玻璃密度影、病灶内血管增粗、小叶内间隔增厚、小叶间隔增厚及胸膜下线比例显著高于境外组。结论COVID-19患者临床症状均以发热、咳嗽多见,境外输入性病例轻型率显著高于境内输入性病例,境外输入性病例肺内病变较境内输入性病例轻,我国对境外输入性病例的疫情防控措施切实可行。Objective To investigate the first chest HRCT imaging manifestations and clinical features of patients diagnosed with imported new coronavirus pneumonia in the domestic group and the overseas group.Methods Retrospective analysis of novel coronavirus pneumonia in 384 confirmed cases of the first chest HRCT imaging and clinical data,including 270 cases in the domestic group and 114 cases in the overseas group.Comparative analysis of the image and clinical data of the two groups was conducted.Results The patients in the domestic group were 5 to 90(48.62±16.25)years old,including 124 males and 146 females;and the patients in the overseas group were 16 to 63(33.45±12.33)years old,including 68 males and 46 females.The main clinical symptoms were fever and cough.The proportion of non-focus(light)in the domestic group was significantly lower than that in the overseas group;the proportion of multiple lesions in the domestic group was significantly higher than that in the overseas group;the proportion of two or more lobes involvement in the domestic group was significantly higher than that in the overseas group;the incidence of lesions in each lobe in the domestic group was significantly higher than that in the overseas group;and the proportion of ground glass density shadow,blood vessel thickening,interlobular septal thickening,interlobular septal thickening and pleural subline in the domestic group was significantly higher than that in the overseas group.Conclusion The clinical symptoms of COVID-19 patients are more common with fever and cough.The mild rate in oversea imported cases is significantly higher than domestic imported cases.Intrapulmonary lesions in imported cases are less severe than those in domestic cases.Measures to prevent and control the epidemic situation of imported cases in China are feasible.
