A 25-year-old African-American woman with end-stage renal disease presented with new-onset heart failure. Transthoracic echocardiography indicated a significantly hyperechoic myocardium, and computed tomography noted a circumferential hyperattenuated myocardium. Endomyocardial biopsy revealed focal interstitial and intramyocyte calcium deposition in the heart, confirming a rare diagnosis of massive myocardial calcium deposition. (Level of Difficulty: Beginner.).
