Purpose

CT imaging has been a detrimental tool in the diagnosis of COVID-19, but it has not been studied thoroughly in pediatric patients and its role in diagnosing COVID-19.

Methods

27 pediatric patients with COVID-19 pneumonia were included. CT examination and molecular assay tests were performed from all participants. A standard checklist was utilized to extract information, and two radiologists separately reviewed the CT images.

Results

The mean age of patients was 4.7 ± 4.16 (mean ± SD) years. Seventeen patients were female, and ten were male. The most common imaging finding was ground-glass opacities followed by consolidations. Seven patients had a single area of involvement, five patients had multiple areas of involvement, and four patients had diffuse involvement. The sensitivity of CT imaging in diagnosing infections was 66.67%. Also, some uncommon imaging findings were seen, such as a tree-in-bud and lung collapse.

Conclusion

CT imaging shows less involvement in pediatric compared to adult patients, due to pediatric patients having a milder form of the disease. CT imaging also has a lower sensitivity in detecting abnormal lungs compared to adult patients. The most common imaging findings are ground-glass opacities and consolidations, but other non-common imaging findings also exist.

COVID-19 儿科患者的临床和放射学特征：关注影像学表现。

目的

CT 成像一直是诊断 COVID-19 的有害工具，但尚未在儿科患者及其在诊断 COVID-19 中的作用进行彻底研究。

方法

纳入了 27 名 COVID-19 肺炎的儿科患者。所有参与者都进行了 CT 检查和分子检测。使用标准检查表提取信息，两名放射科医生分别查看 CT 图像。

结果

患者的平均年龄为 4.7 ± 4.16（平均值 ± SD）岁。17名患者为女性，10名患者为男性。最常见的影像学表现是磨玻璃影，随后是实变。7名患者有单个受累区域，5名患者有多个受累区域，4名患者有弥漫性受累。CT影像诊断感染的敏感性为66.67%。此外，还观察到了一些不常见的影像学表现，例如树芽和肺塌陷。

结论

CT 成像显示，与成人患者相比，儿科患者的受累程度较低，因为儿科患者的病情较轻。与成年患者相比，CT 成像在检测肺部异常方面的灵敏度也较低。最常见的影像学表现是磨玻璃影和实变，但也存在其他不常见的影像学表现。
