Cardiac Mass, Bacteremia, and Embolic Stroke.

ABSTRACT:

Background

Cardiac masses may mimic tumors or vegetations. Differentiation is essential, particularly in the context of bacteremia and embolic complications.

Case summary

A 75-year-old man presented with fatigue, myalgia, and new-onset atrial fibrillation. Transesophageal echocardiography revealed a mitral valve mass with features suggestive of fibroelastoma or myxoma. Blood cultures were positive for Streptococcus mitis. The patient subsequently developed an intracerebral hemorrhage requiring craniotomy. Serial imaging demonstrated resolution of the mitral valve mass, supporting a diagnosis of vegetation.

Discussion

Diagnosis of infective endocarditis requires integration of clinical context, microbiologic data, and serial imaging rather than reliance on echocardiogr
