新型冠状病毒肺炎20例CT表现

CT features of COVID-2019: a study of 20 cases

目的探讨新型冠状病毒肺炎(coronavirus disease 2019,COVID-19)的胸部CT影像学表现,为早期诊断提供影像学依据。方法回顾性分析收治的20例新型冠状病毒核酸阳性患者的年龄、性别、临床表现、流行病学史、实验室检查结果及胸部CT的影像学资料。结果 20例患者中男13例,女7例,年龄27~73岁。19例患者有发热、干咳的临床表现。19例在影像学上表现为单侧肺或者双侧肺中外带肺野或胸膜下磨玻璃样病灶,病灶处于动态变化中,具有多样性、多灶性的特点。增粗血管穿行病灶内在本病中较为常见。胸腔积液少见。结论 COVID-19的影像学具有一定的特征,结合流行病学史、临床特点,可对COVID-19作出初步诊断。

Objective To investigate imaging manifestations of coronavirus disease(COVID-19), thus to provide evidence for early diagnosis of COVID-19. Methods CT imaging data and clinical findings(age, sex, clinical history, epidemiological history, and laboratory tests) of 20 patients were studied.Results Twenty patients(13 men and 7 women) aged 27 to 73 years met the criteria. Among the 20 patients, 19 patients presented with fever and dry cough;19 patients had external or bilateral or unilateral subpleural areas lesions. Meanwhile, the lesions presented with multifocality and diversity. Enlarged vascular lumens and blood vessel penetration sign were common, while pleural effusion was rare. Conclusion The imaging appearance of COVID-19 had certain specific characteristics. When patients have typical imaging features combined with epidemiological history and clinical manifestations, the diagnosis of COVID-19 should be considered.
