Multisystem Inflammatory Syndrome in Children

BACKGROUND: As the number of coronavirus disease 2019 (COVID-19) cases increases globally, more cases of a rare COVID-19–associated disease process are being identified in the pediatric population. This syndrome is referred to as multisystem inflammatory syndrome in children (MIS-C). Clinical manifestations of the syndrome vary and include one or a combination of the following: vasodilatory shock, cardiogenic shock, Kawasaki-like disease, cytokine storming, coronary artery dilatation, and aneurysms. CASE REPORT: This case report describes the presentation, findings, workup, and treatment for a 9-year-old boy diagnosed with MIS-C. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? It is important to recognize MIS-C, as it shares many of the same features as other disease processes, for example, Kawasaki disease and toxic shock syndrome, but has different complications if left untreated.
