A 67-year-old man was admitted to our hospital due to chest tightness induced by activity that had started about 2 months earlier. Electrocardiography revealed left ventricular hypertrophy with negative T-waves in leads I, II, aVL, aVF, and V2 to V6. His troponin and N-terminal pro-brain natriuretic peptide levels were normal. Coronary angiography showed 70% stenosis of the proximal left anterior descending coronary artery. However, there was a mass shadow on the apex of the left ventricle, the position of which was fixed; there was no abnormal swing in the contraction of the heart chamber (Figure 1 and Video 1). Possible underlying etiologies included pericarditis, myocarditis, and intracardiac tumor in the left ventricle or metastatic adenocarcinoma; therefore, we performed cardiac magnetic resonance imaging, which resulted in a diagnosis of ventricular apical hypertrophic cardiomyopathy with intramyocardial calcification (Figure 1). Intramyocardial calcification can exist only in the heart chamber, with no calcification in other parts.
