Background: Primary yolk sac tumor of the mediastinum is an extremely rare and highly malignant neoplasm, affecting mainly young men. Method and result: This case report describes a 60-year-old man with a mediastinal yolk sac tumor and infiltrating the heart. A large mobile mass was found in the right atrium by transthoracic echocardiography, and myxoma was suspected. However, contrast-enhanced 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-body positron emission tomography-computed 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. This patient significantly benefited from the chemotherapy. Conclusion: Multimodal imaging plays a vital role in the diagnostic workup and management for cardiac mass.
