The images show areas of thin myocardial outpouching located in the anterior and apex of left ventricle that has a wide neck, most compatible with true left ventricular aneurysm. Thick mural calcification of aneurysmal dilatation is seen with internal thrombus formation. Also, bilateral pleural effusion and inserted venous catheter are noted.

Discussion (Related Text)
LV aneurysms are most commonly caused by myocardial infarction. True aneurysms are defined as areas of thinned myocardium which are dyskinetic and involve the full thickness of the wall. On the other hand, pseudoaneurysms are a result of rupture of the ventricular free wall, contained by overlying adherent pericardium. They typically have a neck narrower than the diameter of the aneurysm and are more often located in the posterior and lateral wall segments, in contrast to true aneurysms, which are more often seen in the anterior wall and apex, and have a wide neck. More importantly, pseudoaneurysms have a higher risk of rupture and thus, a surgical approach to management is often undertaken. This risk is estimated to be between 30 and 45%, based on older studies.
