Rubella myopericarditis and cardiac tamponade: a case report

A 20-year-old male patient with ulcerative proctitis presented with a fever and chest pain. He was diagnosed with rubella-associated myopericarditis due to pericardial rub, elevated troponin I, ST elevation, and positive rubella-immunoglobulin M. The patient subsequently developed cardiac tamponade but responded well to pericardial drainage and antiinflammatory therapy. Notably, he lacked the classic rubella rash and lymphadenopathy. This case highlights the rare but potential complication of rubella-induced myopericarditis with tamponade, and the importance of considering this diagnosis in the absence of typical rubella symptoms.
