Community-associated bacterial pericarditis is rare, but 4 patients with pericardial involvement related to strains of community-associated methicillin-resistant Staphylococcus aureus presented to 2 hospitals in Alameda County from 2005 to 2009. One case likely resulted from hematogenous spread from a soft-tissue abscess, one from direct invasion from contiguous lung, and 2 from either hematogenous spread or spread from contiguous infection. Community-associated methicillin-resistant S. aureus needs to be considered in the differential diagnosis of pericarditis.
