摘　　要：目的探讨首次胸部高分辨率CT(HRCT)阴性者的新型冠状病毒感染患者的影像学表现及临床特点。方法回顾性分析50例首次胸部HRCT阴性的新型冠状病毒感染患者的影像及临床资料。结果 5例无症状感染者及30例新型冠状病毒肺炎(COVID-19)轻型患者,肺内未见病灶;13例普通型患者,2例重型患者。普通型及重型患者肺内病灶表现:累及单个肺叶3例,累及2个肺叶3例,累及3个及以上肺叶9例;磨玻璃影15例,病灶内血管增粗14例,胸膜下线7例,铺路石征6例,环礁征2例。结论无症状感染者及COVID-19轻型患者多为潜在传染源,需高度警惕;部分COVID-19轻型患者可发展为普通型、重型或危重型。Objective To investigate the image and clinical data initial negative chest HRCT patients with severe acute respiratory syndrome coronavirus 2 infection. Methods Retrospective analysis of the imaging and clinical data of 50 initial negative HRCT patients with severe acute respiratory syndrome coronavirus 2 infection. Results No lung lesion was found in 30 mild patients and 5 asymptomatic patients. There were 13 common patients and 2 severe patients. Intrapulmonary lesions were observed in common and severe patients. Single lobe involvement, 2 lobes involvement, 3 or more lobes involvement, ground glass opacity, vascular thickening, pleural line, and paving stones were observed in 3, 3, 9, 15, 14, 7, 6 and 2 cases, respectively. Conclusion Mild patients and asymptomatic infected patients with COVID-19 are potential sources of infection.
