EKG may show ischemia, infarction or tamponade depending on presentation (4). CXRay may show mediastinal enlargement or pleural effusion (4). Diagnostic test of choice is often coronary angiography that is the gold standard before therapeutic decision-making (5). CT or MRI scanning can also accurately define the extent and size of the aneurysm and the associated complications (4). Echocardiography may show a mass as well (4).
