This study was to collect clinical features and computed tomography (CT) findings of Influenza-Like Illness (ILI) cases, and to evaluate the correlation between clinical data and the abnormal chest CT in patients with the Influenza-Like Illness symptoms. Patients with the Influenza-Like Illness symptoms who attended the emergency department of The Six Medical Center of The PLA General Hospital from February 10 to April 1, 2020 were enrolled. Clinical and imaging data of the enrolled patients were collected and analyzed. The association between clinical characteristics and abnormal chest CT was also analyzed. A total of 148 cases were enrolled in this study. Abnormalities on chest CT were detected in 61/148 (41.2%) patients. The most common abnormal CT features were as follows: patchy consolidation 22/61(36.1%), ground-glass opacities 21/61(34.4%), multifocal consolidations 17/61(27.9%). The advanced age and underlying diseases were significantly associated with abnormal chest CT. Abnormal chest CT is a common condition in Influenza-Like Illness cases. The presence of advanced age and concurrent underlying diseases is significantly associated with abnormal chest CT findings in patients with ILI symptoms. The chest CT characteristic of ILI is different from the manifestation of COVID-19 infection, which is helpful for differential diagnosis.
本研究旨在收集流感样疾病（ILI）患者的临床特征和计算机断层扫描（CT）结果，并评估ILI 症状患者的临床数据与异常胸部 CT 之间的相关性。本研究纳入了 2020 年 2 月 10 日至 4 月 1 日期间在解放军总医院第六医疗中心急诊科就诊的ILI 症状患者。收集了入组患者的临床和影像学数据，并对其进行了分析。还分析了临床特征与异常胸部 CT 之间的相关性。本研究共纳入 148 例患者。61/148（41.2%）患者胸部 CT 异常。最常见的异常 CT 特征如下：斑片状实变 22/61（36.1%），磨玻璃影 21/61（34.4%），多灶性实变 17/61（27.9%）。高龄和基础疾病与异常胸部 CT 显著相关。异常胸部 CT 在ILI 患者中较为常见。高龄和合并基础疾病与 ILI 症状患者的异常胸部 CT 表现显著相关。ILI 的胸部 CT 特征与 COVID-19 感染的表现不同，有助于鉴别诊断。
