Key result
Echocardiography identifies primary pericardial synovial sarcoma after two years of recurrent effusion and fever.
Why the study?
Primary pericardial synovial sarcoma is an extremely rare disease with dismal prognosis and may present with systemic symptoms without apparent pericardial mass on imaging, complicating diagnosis.
Case Report (n=1)
Highlights the diagnostic challenge of primary pericardial synovial sarcoma presenting with systemic symptoms and recurrent pericardial effusion without an apparent mass initially.
Systemic symptoms without visible mass may delay primary pericardial synovial sarcoma diagnosis; extends known presentations but remains hypothesis-generating.
Primary pericardial synovial sarcoma is an extremely rare disease with a dismal prognosis. Its main presenting symptoms are a large pericardial effusion, signs of cardiac tamponade, and visualization of a pericardial mass on echocardiography. However, the systemic symptoms of fever, cough, and night sweats may present a clinical picture without any apparent pericardial mass on diagnostic imaging, potentially impeding the diagnosis. We report the case of a 34-year-old patient with fever and recurrent pericardial effusion for 2 years, who was diagnosed with primary pericardial synovial sarcoma after 2-year follow-up echocardiography.
