The detection of masses is prevalent in heart diagnostic techniques including echocardiography and cardiac imaging. The most
frequent masses are tumor, vegetation and thrombus, which are easily confused with each other because the characteristics of the
mass can vary depending on regional location, mass morphology and clinical syndrome. Surgical and histopathological
interventions are required for a conclusive diagnosis. Infectious endocarditis (IE) is a bacterial infection of the endocardium that can
affect a heart valve or an implanted cardiac device. It is linked to vegetation that can be found on heart valves or any implant
devices, as was the case in our patient and it can spread through the vegetation of various sizes.
