Recurrent pericarditis associated with human coronavirus (HKU1) infection in a patient with systemic lupus erythematosus (SLE).

The presence of human coronavirus HKU1 infection associated with pericardial inflammation is not reported. We are reporting a young woman with systemic lupus erythematosus, who was positive for HKU1 during her pericarditis flare. Diagnostic imaging demonstrated pericardial effusion, edema, and late gadolinium enhancement on cardiac magnetic resonance imaging and echocardiography. She was on multiple anti-inflammatory medications and achieved remission with anakinra. Her management and a brief literature review is also presented.
