Imaging Features of Pediatric COVID-19 on Chest Radiography and Chest CT: A Retrospective, Single-Center Study

Abstract

© 2020 The Association of University RadiologistsRationale and Objectives: This study aims to reveal the imaging features of Coronavirus Disease 2019 (COVID-19) in children. Materials and Methods: Sixty-nine chest radiographs and 37 chest CT examinations of 74 children (36 male; median (interquartile range) age:11 (6.25–15) years, 38 female; median (interquartile range) age: 12 (5.75–16) years) with positive real-time reverse transcription-polymerase chain reaction results between March 10 and May 31, 2020, were evaluated in this retrospective study. Differences in 0– 0.05). The rate of ground-glass opacities with or without consolidation (17/37, 45.94%) was higher than consolidation alone (6/37, 16.2%). Feeding vessel sign (16/37, 43.2%), halo sign (9/37, 24.3%), pleural thickening (6/37, 16.2%), interlobular interstitial thickening (5/37, 13.5%), and lymphadenopathy (3/37, 8.1%) were other imaging findings. Conclusion: Unilateral or bilateral distributed ground-glass opacities often associated with feeding vessel sign, halo sign, and pleural thickening on chest CT without significant differences between age groups were findings of COVID-19 in children.
