A large mobile mass was found in the right atrium by transthoracic echocardiography, and myxoma was suspected. However, contrast\u2010enhanced ultrasonography imaging revealed a remarkable enhancement in the mass. Highly metabolized mass was not only found in the right atrium, also in superior vena cava and right superior mediastinum by whole\u2010body positron emission tomography\u2010computed tomography. Supraclavicular lymph node biopsy confirmed the tumor as a primary mediastinum yolk sac. The tumor started to shrink during chemotherapy and AFP levels decreased.
