Coronavirus disease 2019 (COVID-19) outbreak, first reported in Wuhan, China, has rapidly swept around the world just within a month, causing global public health emergency. In diagnosis, chest computed tomography (CT) manifestations can supplement parts of limitations of real-time reverse transcription polymerase chain reaction (RT-PCR) assay. Based on a comprehensive literature review and the experience in the frontline, we aim to review the typical and relatively atypical CT manifestations with representative COVID-19 cases at our hospital, and hope to strengthen the recognition of these features with radiologists and help them make a quick and accurate diagnosis.Key Points• Ground glass opacities, consolidation, reticular pattern, and crazy paving pattern are typical CT manifestations of COVID-19.• Emerging atypical CT manifestations, including airway changes, pleural changes, fibrosis, nodules, etc., were demonstrated in COVID-19 patients.• CT manifestations may associate with the progression and prognosis of COVID-19.
新型冠状病毒病 2019（COVID-19）疫情，首次在中国武汉报告，在短短一个月内迅速席卷全球，引发全球公共卫生紧急事件。在诊断方面，胸部计算机断层扫描（CT）表现可以补充实时逆转录聚合酶链反应（RT-PCR）检测的部分局限性。基于全面的文献复习和一线经验，我们旨在回顾我院具有代表性的 COVID-19 病例的典型和相对非典型 CT 表现，希望增强放射科医生对这些特征的认识，并帮助他们快速准确地诊断。
磨玻璃影、实变、网状影和铺路石征是 COVID-19 的典型 CT 表现。
COVID-19 患者表现出新兴的非典型 CT 表现，包括气道改变、胸膜改变、纤维化、结节等。
CT 表现可能与 COVID-19 的进展和预后相关。
