Subacute COVID-19 Infection Presenting as Indolent Large Pericardial Effusion

Reports of complications as a result of COVID-19 infection are emerging since the virus became a pandemic. Although not fully understood, reports show that the COVID-19 virus has shown acute pericardial involvement resulting from this infection. It can cause a wide range of manifestations from minimal effusion to large effusion with tamponade; however, there is little or no data on an indolent course of COVID-19 infection and its resulting manifestations. Here we describe a patient who had minimal disease symptoms for weeks, resulting in sizeable pericardial effusion formation.
