Metastatic cardiac cancers are more prevalent than generally realized. So prompt recognition is mandatory if any cardiovascular manifestations develop in a patient with a malignant lesion elswhere in the body. Sixty-five year old male patient who had past history of resected chondrosarcoma on the 10th rib of left side presented as a local recurrence and dyspnea. Chest C-T findings demonstrated thrombose on right atrium and superior vena cava. Two-dimensional echocardiographic study showed mild pericardial effusion with a small mass attached to the visceral pericardium and a huge mass occupying nearly entire right atrial chamber with extension to superior vena cava. These findings are suggestive of cardiac metastasis of chon- drosarcoma.
