True left ventricular aneurysms are most frequently seen after acute transmural myocardial infarction. These aneurysms are distinct from apical left ventricular pseudoaneurysms, which can also be seen in ischemia, and have a different treatment course. A major dilemma for clinicians is using echocardiographic information to make this distinction. Coronary angiography aids in this distinction; however, in the case of normal coronaries alternate etiologies must be considered. The differential for a patient with a left ventricular aneurysm and normal coronaries or no prior cardiac surgery is broad and includes traumatic, infectious and infiltrative causes. In this e-challenge, we present an unusual cause of a left ventricular apical aneurysm in a patient with normal coronary arteries residing in the United States.
