A 72-year-old man with a stage IV small intestinal neuroendocrine tumor presented to our cardiology clinic as a referral for an abnormal positron emission tomography–computed tomography scan with an intense gallium uptake in the heart. Follow-up cardiac magnetic resonance was suggestive of myocardium infiltration by the neuroendocrine tumor with late gadolinium enhancement and T1 time elevation. (Level of Difficulty: Intermediate.)
