Imaging Findings in Pediatric COVID-19: A Review of Current Literature

The recent COVID-19 pandemic has afflicted over 200 million individuals to date, with many different organ systems involved. The pediatric involvement has been variable, but of note is the risk of cardiac disease in pediatric COVID-19 patients. We review here the cardiac involvement in pediatric patients with COVID-19. Several studies highlight a possible cardiotropic nature of SARS-CoV-2, and describe the disease severity in myocarditis, both symptomatic and occult, as well as MIS-C. We describe the expected clinical course of these patients and note the lack of long-term follow-up data and the concerning prevalence of continued abnormal findings on follow-up imaging. With this paucity of long-term cardiac data, we recommend consideration of advanced imaging for pediatric patients with cardiac symptoms and/or elevation of cardiac serum biomarkers.
