Context: This systematic review explores the radiographic manifestations of coronavirus disease 2019 (COVID-19) and multisystem inflammatory syndrome in children (MIS-C) in pediatric patients. The initial focus of the COVID-19 pandemic was on adults, as it originated from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), leading to insufficient understanding of its effects in children. Most pediatric COVID-19 cases are mild or asymptomatic, but a minority may develop severe pneumonia. Additionally, the potential for children to contribute to virus transmission complicates the dynamics of the pandemic. Results: This review outlines key radiological findings in pediatric COVID-19, focusing on chest radiography, chest computed tomography (CT), and lung ultrasound (US). The MIS-C, associated with COVID-19, is characterized by severe multi-organ inflammation, necessitating timely imaging for diagnosis and management. Common findings include heart failure and acute respiratory distress syndrome (ARDS). Conclusions: The as low as reasonably achievable (ALARA) principle guides pediatric imaging, emphasizing radiation minimization, with low-dose CT as an alternative. Further research is essential to improve understanding of pediatric COVID-19 and MIS-C.
