A 39-year-old man presented with a one-year history of intermittent dyspnea on exertion associated with right upper quadrant abdominal pain. A chest radiograph was normal. An intracardiac mass was found incidentally by abdominal ultrasonography, which revealed a normal hepatobiliary system. Transthoracic echocardiography revealed a wide-based tumor located in the right atrium (RA) (Figure, A). There was no evidence of tumor mobility or pericardial effusion. Ultrafast computed tomography confirmed a huge tumor (6×4×3 cm) with soft tissue density inside of the RA (Figure, B). At operation, a sponge-like tumor attached to the anterior RA wall was excised en bloc (Figure, C). On histological examination, it was a hemangioma (Figure, D). The patient made an uneventful recovery and was discharged 1 week later.
