Figure 6. Left ventricular (LV) aneurysm with calcification and intracavitary thrombus in a 65-year-old male with old myocardial infarction (MI). Axial delayed-phase cardiac computed tomography image obtained at the end-systolic phase shows an LV apical aneurysm with calcification (arrow), intracavitary thrombus (arrowheads), and delayed transmural hyperenhancement of the apical to mid septal LV myocardium (thin arrows). Four-chamber delayed-phase cardiac magnetic resonance image obtained at the mid-diastolic phase shows an apical aneurysm with intracavitary thrombus (arrowheads) and diffuse subendocardial delayed hyperenhancement of the LV septum and lateral wall (arrows), consistent with old MI.
