Abstract
Hyperinflammation is a key component of severe coronavirus disease 2019 (COVID-19) and is associated with poor outcomes. It is imperative to distinguish severe COVID-19 from hyperinflammatory syndromes such as multisystem inflammatory syndrome (MIS) and hemophagocytic lymphohistiocytosis. There is a subset of post-COVID-19 patients who present with some symptoms characteristic of MIS in adults (MIS-A) yet do not meet all the criteria for a diagnosis. We describe the unique case of a patient with this kind of presentation who clinically improved following tocilizumab and corticosteroid usage.
