A rare case of multisystem inflammatory syndrome in adults-a diagnostic dilemma

Abstract

Multisystem inflammatory syndrome (MIS) is a rare and severe post-infectious inflammatory disorder involving multiple systems (cardiovascular, gastrointestinal, dermatologic, nervous system, and haematological) without significant respiratory involvement. It is predominantly seen in children but sometimes in adults, usually after 3-6 weeks of COVID-19 infection or vaccination. It is postulated to be due to immune dysregulation. This case report adds to the limited literature available on post COVID MIS in adults, emphasizing how to reach the diagnosis after ruling out other differentials. Timely initiation of treatment gives gratifying results in most patients.
