COVID-19 (coronavirus disease 2019) is a recently emerged pulmonary infection caused by severe acute respiratory syndrome coronavirus (SARS-CoV-2). It started in Wuhan, China, in December 2019 and led to a highly contagious disease. Since then COVID-19 continues to spread, causing exponential morbidity and mortality and threatening economies worldwide. While the primary diagnostic test for COVID-19 is the reverse transcriptase-polymerase chain reaction (RT-PCR) assay, chest CT has proven to be a diagnostic tool of high sensitivity. A variety of conditions demonstrates CT features that are difficult to differentiate from COVID-19 rendering CT to be of low specificity. Radiologists and physicians should be aware of imaging patterns of these conditions to prevent an erroneous diagnosis that could adversely influence management and patients' outcome. Our purpose is to provide a practical review of the conditions that mimic COVID-19. A brief description of the forementioned clinical conditions with their CT features will be included.
2019冠状病毒病（COVID-19）是由严重急性呼吸综合征冠状病毒2（SARS-CoV-2）引起的一种新出现的肺部感染。它于2019年12月在中国武汉开始出现，并引发了一种高传染性疾病。从那时起，COVID-19持续传播，导致发病率和死亡率呈指数级上升，并对全球经济构成威胁。虽然COVID-19的主要诊断测试是逆转录聚合酶链反应（RT-PCR）检测，但胸部CT已被证明是一种高灵敏度的诊断工具。多种病症表现出与COVID-19难以区分的CT特征，导致CT的特异性较低。放射科医生和内科医生应了解这些病症的影像学表现，以防止错误诊断，因为这可能会对治疗管理和患者预后产生不利影响。我们的目的是对类似COVID-19的病症进行实用的综述。文中将包括对上述临床病症及其CT特征的简要描述。
