Cardiac pseudoaneurysm is a rare but potentially lethal complication of myocardial infarction. Clinical manifestations may be nonspecific or, in some cases, may even be silent. Therefore, high clinical suspicion should be maintained when a patient becomes unstable after a myocardial event. Efficient use of imaging examinations is crucial in providing an accurate diagnosis and, thereafter, timely and appropriate treatment. The authors report a case involving a giant left ventricular pseudoaneurysm that required both transthoracic echocardiography and magnetic resonance imaging to reach the correct diagnosis. The pathology, clinical presentation, diagnostic work-up and treatments of cardiac pseudoaneurysms are reviewed.
