    Background: Despite advancements in vaccination and the transition from pandemic to endemic, SARS-CoV-2 continues to pose a medical challenge, particularly among children. In this context, imaging diagnostics, such as chest x-rays, are crucial to the initial treatment of patients. This study aims to characterize the radiological findings in pediatric patients with confirmed SARS-CoV-2 infection in Colombia between April 2020 and November 2021, as well as their potential association with intensive care admission. Methods: In Colombia, a multicenter cohort comprised patients aged 29 days to 17 years with confirmed SARS-CoV-2 infection and chest X-ray administered within 72 hours of hospitalization. In two separate groups, four radiologists evaluated the images. A fifth radiologist reviewed all the X-rays; and subsequently, these readings were used to calculate the kappa coefficient and to resolve discrepancies among the other radiologists. The results were compared to admission to intensive care. Results: Analysis was conducted on 392 patients with a mean age of 2 years, the majority of whom (42%) were infants. Sixty-eight percent of the radiographs had normal results. Peribronchial thickening and interstitial opacity were the most common aberrant findings (59%), followed by alveolar opacity (12%). 88 percent of findings were bilateral. The most common association between peribronchial thickening and intensive care admission was ventilatory failure. Interobserver agreement was low for peribronchial thickening (kappa = 0.1), but higher for consolidations and alveolar opacities (kappa = 0.4 and 0.5, respectively). Conclusion: In pediatric patients with SARS-CoV-2, radiological findings are nonspecific and interobserver agreement is minimal. Although consolidation and alveolar opacities demonstrated greater concordance, they were not associated with clinical differences; therefore, chest radiography is not considered useful for determining the severity of COVID-19 in children.
