Primary cardiac tumors are rare in all age groups, with a reported prevalence of 0.001–0.03% in autopsy series. We report the case of a 37-year-old man, with no relevant medical history, who was admitted to the emergency department with sudden-onset right hemiparesis. Diagnostic studies revealed a small hypodense area in the left putamen and he was admitted to the stroke unit with a diagnosis of ischemic stroke. During investigation of the cause of stroke in such a young patient, he underwent transthoracic echocardiography, which showed a mass attached to the anterior leaflet of the mitral valve (Figure 1). Transesophageal echocardiography was then performed to clarify the picture, which confirmed a small echodense pedunculated mass, 0.5 cm2 in size, with well-defined borders, features typical of a fibroelastoma (Figures 2 and 3), attached to the atrial surface of the anterior mitral valve leaflet without causing mitral regurgitation (Figure 4). The rest of the echocardiographic examination revealed an estimated left ventricular ejection fraction of 65% and no other valvular abnormalities. The patient was subsequently referred to the cardiothoracic surgery center for surgical excision of the mass. Macroscopic examination showed a 0.6-cm whitish spiculated nodule with a soft elastic consistency. Histopathological study revealed cardiac myxoma. We present this case to highlight the unusual presentation, particularly its echocardiographic features.
