Cardiac Metastasis Presenting With ST-Segment Elevation

Cardiac metastasis is an uncommon condition that may be missed owing to variability in patient presentation. An 81-year-old man with a history of metastatic squamous cell carcinoma, presenting with heart failure, showed persistent ST-segment elevation on an electrocardiogram. Chest computed tomography, performed to exclude pulmonary embolism, demonstrated possible cardiac mass that was evaluated subsequently with echocardiography and cardiac magnetic resonance. This case shows the importance of multimodality imaging in diagnosing cardiac metastasis in cancer patients with cardiac symptoms. Although the mechanisms are unclear, persistent ST-segment elevations should be considered as a potential clue to the presence of cardiac metastasis.
