In this study, we aimed to evaluate the thorax Computed Tomography (CT) findings of pediatric patients diagnosed with coronavirus disease-19 (COVID-19) and to discuss these findings in light of the results of adult patients from the literature.
The CT scans of pediatric patients (1-18 years old) with a diagnosis of COVID-19 by reverse transcriptase-polymerase chain reaction (RT-PCR) in our hospital between March 2020 and January 2021 were retrospectively reviewed. The scans were interpreted regarding the distribution and localization features, and involvement patterns including ground-glass opacity, consolidation, halo/reversed halo sign, interlobular septal thickening, air bronchograms and bronchiectasis. The frequencies of these findings in pediatric cases in our study were recorded.
A total of 95 patients with a mean age of 13±4.6 years were included in this study. Among them, 34 (36%) had lesions associated with COVID-19 on CT scans. Bilateral involvement was detected in 15 (44%) while unilateral in 19 (56%) patients. Eighteen (53%) patients had single lobe involvement. In 16 (47%) patients a solitary lesion was detected and in 18 (53%) multiple lesions were present. Ground-glass opacity appearance was observed in 28 (82%), consolidation in 9 (26%), and ground-glass opacity with consolidation in 8 (24%), halo sign in 9 (26%), reversed halo sign in 2 (6%), interlobular septal thickening (interstitial thickening) in 1 (3%) patients.
As symptoms are relatively milder in children with COVID-19, CT findings are less extensive than in adults. It is essential to know the thorax CT findings that aid in the diagnosis and follow-up of the disease.
在本研究中，我们旨在评估经逆转录-聚合酶链反应（RT-PCR）诊断为 2019 冠状病毒病（COVID-19）的儿科患者的胸部计算机断层扫描（CT）结果，并结合文献中成人患者的结果讨论这些发现。
回顾性分析我院 2020 年 3 月至 2021 年 1 月间经 RT-PCR 诊断为 COVID-19 的儿科患者（1-18 岁）的 CT 扫描。根据分布和定位特征、受累模式（包括磨玻璃影、实变、晕征/反晕征、小叶间隔增厚、空气支气管征和支气管扩张）对扫描进行解读。记录本研究中儿科病例的这些发现频率。
本研究共纳入 95 例患者，平均年龄为 13±4.6 岁。其中，34 例（36%）CT 扫描显示与 COVID-19 相关病变。15 例（44%）为双侧受累，19 例（56%）为单侧受累。18 例（53%）患者为单叶受累，16 例（47%）患者存在单个病变，18 例（53%）患者存在多个病变。28 例（82%）患者表现为磨玻璃影，9 例（26%）患者表现为实变，8 例（24%）患者表现为磨玻璃影伴实变，9 例（26%）患者表现为晕征，2 例（6%）患者表现为反晕征，1 例（3%）患者表现为小叶间隔增厚（间质增厚）。
由于儿童 COVID-19 患者的症状相对较轻，因此 CT 表现不如成人广泛。了解有助于诊断和随访疾病的胸部 CT 表现至关重要。
