Pericarditis purulenta por Staphylococcus aureus resistente a meticilina en un paciente con diálisis peritoneal: una afección cardíaca por una infección cutánea. Reporte de caso

Pericarditis is a relatively rare infectious/inflammatory condition observed in clinical hospital settings. The purulent pericarditis being the most uncommon manifestation and associated with the highest mortality rates. We detail the case of a 53-year-old male undergoing peritoneal-based renal replacement therapy who developed purulent pericarditis attributed to methicillin-resistant Staphylococcus aureus (MRSA), secondary to a skin and soft tissue source. This represents the first reported case with such features. Despite their rarity, such events carry a significant short-term mortality risk, emphasizing the importance of timely diagnosis. This manuscript aims to emphasize that despite its rarity, MRSA purulent pericarditis carries a significant risk of short-term mortality, hence the importance of timely diagnosis and treatment.
