Abstract
A 58-year-old male patient with incessant ventricular tachycardia was referred to cardiac magnetic resonance for scar assessment. He was found to have metastatic amelanotic melanoma of the heart. The cardiac magnetic resonance-based diagnosis of cardiac malignancy critically altered the subsequent clinical management. There was a marked response to immunotherapy as evidenced by follow-up imaging studies. (Level of Difficulty: Intermediate.).
