Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the current outbreak of Coronavirus disease 2019 (COVID-19). Although imaging should not be used for first-line screening or diagnosis, radiologists need to be aware of its imaging features, and those of common conditions that may mimic COVID-19 pneumonia. In this Pictorial Essay, we review frequently encountered conditions with imaging features that overlap with those that are typical of COVID-19 (including other viral pneumonias, chronic eosinophilic pneumonia, and organizing pneumonia), and those with features that are indeterminate for COVID-19 (including hypersensitivity pneumonitis, pneumocystis pneumonia, diffuse alveolar hemorrhage, pulmonary edema, and pulmonary alveolar proteinosis).
严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）是导致 2019 年冠状病毒病（COVID-19）当前疫情的病原体。尽管影像学检查不应用于一线筛查或诊断，但放射科医生需要了解其影像学特征，以及可能模拟 COVID-19 肺炎的常见疾病的影像学特征。在本影像学专题文章中，我们复习了具有与 COVID-19 典型表现（包括其他病毒性肺炎、慢性嗜酸性粒细胞性肺炎和机化性肺炎）重叠影像学特征的常见疾病，以及具有非 COVID-19 特征（包括过敏性肺炎、卡氏肺孢子菌肺炎、弥漫性肺泡出血、肺水肿和肺泡蛋白沉积症）的疾病。
