Although chest radiography can be a useful tool in the investigation of lower respiratory tract infections, the extent to which this should be utilized in children with COVID-19 remains unclear. Use of lung ultrasound (US) has been advocated to detect early pulmonary abnormalities in adults, however little published evidence exists regarding its clinical usefulness in children. Chest computed tomography (CT) has been proposed to identify adults with false-negative real-time reverse transcriptase polymerase chain reaction (PCR) results. However, given that most children present with mild symptoms or are asymptomatic, the additional radiation dosage for screening CT or preoperative CT may not be justified. Furthermore, it is unclear whether the characteristic COVID-19 findings in adults are applicable to a pediatric population. The aim of this case series, therefore, was to describe the imaging appearances of a large cohort of children with COVID-19 and to provide some guidelines for pediatric imaging.
