Left ventricular (LV) thrombi may be caused by various conditions, particularly myocardial infarction. In most cases, LV thrombus occurs in patients with a significantly reduced ejection fraction. A LV thrombus is extremely rare in patients with normal LV function. We report a case of LV thrombus initially detected on transthoracic echocardiography and confirmed using cardiac magnetic resonance imaging in a patient with normal LV wall motion. We highlight the rarity of this condition and the usefulness of cardiac magnetic resonance imaging in the diagnosis of LV thrombus.
