Papillary fibroelastoma complicated by Streptococcus sanguinis bacteremia: a rare case of cardiac tumor with embolic events

Fibroelastoma is a rare cardiac tumor that can cause embolization, stroke, myocardial infarction, heart failure, and cardiac arrest. Here, we report the case of a 45-year-old male who presented with right-sided weakness and fever. He was diagnosed with acute right frontal infarction and was found to have Streptococcus sanguinis bacteremia. Upon confirmation of a positive blood culture after 24 hours, treatment for endocarditis was initiated. Transesophageal echocardiography revealed findings highly suggestive of a papillary fibroelastoma (PFE). PFE ought to be regarded as a potential differential diagnosis in individuals who exhibit symptoms of fever, thromboembolism, and persistent bacteremia. Non-invasive imaging such as echocardiography is of great value in the diagnosis of PFE, while surgical resection remains the best treatment modality to overcome current and future associated complications.
