Idiopathic aneurysms involving the left ventricle are considered very rare, and in a majority of instances, they are asymptomatic. In a minority of patients, they may present with cardiac rupture, cardiac tamponade, ventricular arrhythmias, and sudden death. We describe the case of a 21-year-old male patient who was hospitalized for altered mentation and critical left lower limb ischemia because of acute embolic events. Transthoracic echocardiography demonstrated a left ventricular aneurysm and a reduced ejection fraction. Similarly, cardiac computed tomography showed a large left ventricular aneurysm with mobile vegetations representing thrombi. He was managed with therapeutic anticoagulation and recovered uneventfully.
