title: Left ventricular pseudoaneurysm versus aneurysm a diagnosis dilemma.
abstract: Free wall rupture of the left ventricle (LV) is a rare but life-threatening complication of acute myocardial infaction. Very rarely such rupture may be contained by the adhering pericardium creating a pseudoaneurysm. This condition warrants for an emergency surgery. Left ventricular aneurysm is the discrete thinning of the ventricular wall (<5 mm) with akinetic or dyskinetic wall motion causing an out-pouching of the ventricle. Given the propensity for pseudoaneurysms to rupture leading to cardiac tamponade, shock, and death, compared with a more benign natural history for true aneurysms, accurate diagnosis of these conditions is important. True aneurysm, usually, calls for an elective surgery. Clinically differentiating the two conditions remains a challenge. We report the case of a patient with LV pseudoaneurysm, initially diagnosed as true aneurysm at our institution. We have attempted to review the existing literature and discussed the characteristic findings of each entity.
