摘要

目的:分析2019冠状病毒病的CT影像学特征,为临床医生诊断2019冠状病毒病提供一定参考。方法:选择安徽医科大学第一附属医院2019年1月至2019年3月在全国2019冠状病毒病疫情暴发期间的20例住院患者,男10例,女10例,年龄29~71(46.8±11.7)岁,所有病例经新型冠状病毒核酸检测确诊;分析不同随访时间的CT影像图像特征及临床资料。结果:普通型18例,重型2例。CT检查肺内多发病变19例(95%),单发病变1例(5%)。20例病例发现斑片样磨玻璃影19例(95%),病变大多临近胸膜下区。20例患者共100段肺叶,其中发现磨玻璃影病变共58叶(58%);发现斑片样实变影29叶(29%)。住院治疗后,5 d复查胸部CT,8例患者病情进展,12例无明显变化。10 d复查,4例进展,1例无明显变化,15例出现吸收征象,缓解率占75%。15 d后复查随访15例,均表现吸收征象,占100%。结论:2019冠状病毒病的影像特征以磨玻璃样病变为主;两肺常见多发病变,病变多分布在胸膜下区;少有并发胸腔积液或心包积液,不伴有纵膈及肺门肿大淋巴结;治疗10~15 d后开始出现逐渐吸收现象。

Abstract

Objective: To analyze the CT imaging features of 2019 coronavirus disease, and provide some references for clinicians to diagnose novel coronavirus pneumonia. Methods: Twenty hospitalized patients, including 10 males and 10 females, aged 29–71 (46.8±11.7) years old, were selected from January 2019 to March 2019 during the outbreak of 2019 coronavirus disease in the First Affiliated Hospital of Anhui Medical University. The CT image characteristics and clinical data of different follow-up time were analyzed. Results: Eighteen cases were normal type, 2 heavy type. CT examination showed multiple lung lesions in 19 cases (95%), and single lung lesions in 1 case (5%). In 20 cases, 19 cases (95%) had patchy ground glass shadow, most of which were close to the subpleural area. Of 100 pulmonary lobes in 20 patients, 58 lobes (58%) had ground glass shadow lesions. Speckle consolidation was found in 29 leaves (29%). After hospitalization, chest CT was reexamined 5 days later, 8 patients were disease progression and 12 cases showed no significant changes. After 10 days, 4 cases progressed, 1 case showed no significant change, and 15 cases showed signs of absorption (75%). After 15 days, 15 patients were followed up, and all the patients showed signs of absorption (100%). Conclusion: The imaging features of 2019 coronavirus disease infection are mainly ground-glass opacity shadow. Multiple lesions are common in both lungs, mostly in the subpleural area. Pleural effusion or pericardial effusion are rare, and there are no enlarged mediastinal and hilar lymph nodes. Gradual absorption begins 10–15 days after treatment.
