Figure legends
Figure 1 Transthoracic echocardiography showing a large round and high echogenic mass in the left ventricular. M, mass; LV, left ventricle.
Figure 2 Transthoracic echocardiography showing a high echogenic mass attaching to the LV wall epicardium.M, mass; LV, left ventricle.
Figure 3 PET/CT imaging showed masses in the LV and at lateral posterior LV wall near the apex, with local hypermetabolism and high SUVmax,M, mass; LV, left ventricle.
Figure 4 Pathologic examination showed neuroendocrine tumor, equivalent to an atypical carcinoid, with invasion into cardiac striated muscle tissue, which suggested mediastinal tumor metastasis.
