We aimed to compare chest HRCT lung signs identified in scans of differently aged patients with COVID-19 infections.
Case data of patients diagnosed with COVID-19 infection in Hangzhou City, Zhejiang Province in China were collected, and chest HRCT signs of infected patients in four age groups (<18 years, 18-44 years, 45-59 years, ≥60 years) were compared.
Small patchy, ground-glass opacity (GGO), and consolidations were the main HRCT signs in 98 patients with confirmed COVID-19 infections. Patients aged 45-59 years and aged ≥60 years had more bilateral lung, lung lobe, and lung field involvement, and greater lesion numbers than patients <18 years. GGO accompanied with the interlobular septa thickening or a crazy-paving pattern, consolidation, and air bronchogram sign were more common in patients aged 45-59 years, and ≥60 years, than in those aged <18 years, and aged 18-44 years.
Chest HRCT manifestations in patients with COVID-19 are related to patient's age, and HRCT signs may be milder in younger patients.
比较不同年龄段 COVID-19 感染患者的胸部 HRCT 肺部征象。
收集中国浙江省杭州市确诊为 COVID-19 感染患者的病例资料，比较四个年龄组（<18 岁、18-44 岁、45-59 岁、≥60 岁）感染患者的胸部 HRCT 征象。
98 例确诊 COVID-19 感染患者的主要 HRCT 征象为小斑片状、磨玻璃影（GGO）和实变。45-59 岁和≥60 岁年龄组患者双肺、肺叶和肺野受累程度及病变数量均大于<18 岁年龄组。45-59 岁和≥60 岁年龄组患者 GGO 伴间隔增厚或铺路石征、实变和气道征较<18 岁和 18-44 岁年龄组更为常见。
COVID-19 患者的胸部 HRCT 表现与患者年龄有关，年轻患者的 HRCT 征象可能较轻。
