DOI : 10.24953/turkjped.2021.1726 Background. 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.

Methods. 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.

Results. 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.

Conclusions. 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. Keywords : COVID-19, children, computed tomography, chest imaging, pneumonia
