The epidemic of 2019 novel coronavirus, later named as coronavirus disease (COVID-19), began in Wuhan, China in December 2019 and has spread rapidly worldwide. Early diagnosis is crucial for the management of the patients with COVID-19, but the gold standard diagnostic test for this infection, the reverse transcriptase polymerase chain reaction, has a low sensitivity and an increased turnaround time. In this scenario, chest computed tomography (CT) could play a key role for an early diagnosis of COVID-19 pneumonia. Here, we have reported a confirmed case of COVID-19 with an atypical CT presentation showing a "double halo sign," which we believe represents the pathological spectrum of this viral pneumonia.
2019 年新型冠状病毒疫情（简称“新冠肺炎”）于 2019 年 12 月在中国武汉爆发，并迅速在全球蔓延。早期诊断对于新冠肺炎患者的治疗至关重要，但该感染的金标准诊断检测——逆转录聚合酶链反应（RT-PCR）——具有较低的敏感性和较长的周转时间。在这种情况下，胸部计算机断层扫描（CT）可能在新冠肺炎肺炎的早期诊断中发挥关键作用。在这里，我们报告了一例新冠肺炎确诊病例，其 CT 表现不典型，呈现“双晕征”，我们认为这代表了这种病毒性肺炎的病理谱。
