Calcified ventricular aneurysm
Calcified left ventricular aneurysm. These are an uncommon complication of myocardial infarction. The CXR on the left shows some curvilinear calcification (arrows) projected over the left heart border. On the CT image, right, you can clearly see that the calcification is in the wall of the left ventricle, involving the apex and interventricular septum. The affected wall is also much thinner than the remainder of the myocardium, and is bulging slightly. These patients are at risk of sudden death due to arrhythmias.
