These three aortas demonstrate mild, moderate, and severe atherosclerosis from bottom to top. At the bottom, the mild atherosclerosis shows only scattered lipid plaques (arrows). The aorta in the middle shows many more larger whitish plaques. The severe atherosclerosis in the aorta at the top shows extensive ulceration in the plaques (arrows).

This is severe atherosclerosis of the aorta in which the atheromatous plaques have undergone ulceration along with formation of overlying mural thrombus (arrows).
