Left ventricular noncompaction (LVNC) is a rare congenital disease. We herein present less common single photon emission computed tomography (SPECT) images of myocardial perfusion in an adult patient with LVNC. The images revealed segmental and seriously decreased myocardial perfusion with moderate enlargement of the left ventricle. Quantitative electrocardiogram-gated SPECT showed a moderately decreased left ventricular ejection fraction with impaired contractions. The SPECT findings were very similar to those of ischemic cardiomyopathy (ICM). Cardiac magnetic resonance (CMR) and echocardiography confirmed the diagnosis of LVNC. Physicians should be aware of this uncommon cardiomyopathy and conduct comprehensive analyses in order to make a better differential diagnosis.
