Abstract

We report the CT and echocardiographic findings of a tumor-mimicking large vegetation attached to the tricuspid valve (TV) of a 45-year-old man without predisposing factors. Echocardiography revealed a mobile homogeneous echogenic mass attached to the TV. Cardiac CT showed a 4.5 x 2.3 cm irregular low-density mass with scant enhancement in the right ventricle. Based on clinical findings of fever, positive blood culture results for Streptococcus viridans, and pathologic confirmation of the lesion, a diagnosis of infective endocarditis and vegetation was made.
