Inferobasal LV aneurysm with thrombus on CT scan

A CT scan without contrast through the left ventricle (A) shows a calcified aneurysm (arrow) in the inferobasal and septal region of the left ventricle. A CT scan with contrast performed 5 years later (B) shows thrombus within the aneurysm (dashed arrow). The size of the aneurysm is unchanged.
