Conclusion:
Acute pericarditis and pericardial effusion are rare extrapulmonary
presentations of COVID-19, especially without concomitant pulmonary
disease or myocardial injury. A high index of suspicion is necessary to
assure early diagnosis and treatment. Studies are needed to determine
the exact mechanism of acute pericarditis and pericardial effusion in
COVID-19 patients and the optimal therapeutic strategies.
