Computed Tomography Features of Left Ventricular Pseudoaneurysm: A Case Report

Left ventricular pseudoaneurysm is a rare and fatal complication of myocardial infarction. Patients usually die from hemorrhage; therefore, urgent surgical resection is the mainstay of treatment. The most important differential diagnosis for this entity is left ventricular true aneurysm that could be managed with medical treatment. The diagnostic work up of left ventricular abnormal outpouching is well illustrated in the literature; however, less is written about the role of computed tomography angiography (CTA). Hereby, we present a case of left ventricular pseudoaneurysm in a 65-year-old woman who suffered from an ST elevation myocardial infraction six months ago. The echocardiography and chest CTA examinations revealed formation of a large aneurysmal cavity posterolateral to the left ventricle with significant thrombus formation. However, less is written about the role of computed tomography angiography in the diagnostic work up of left ventricular pseudoaneurysm. We present the typical features of left ventricular pseudoaneurysm depicted with CTA.
