File:IPlab4AtheromatousEmboli1IPLab4AtheromatousEmboli1.jpg|This is a gross photograph of the aorta from this patient opened lengthwise with the luminal surface visible. Note the rough surface with ulcerations and adherent thrombotic material. There is a mild dilation (aneurysm) at the distal aorta just at the bifurcation with an accumulation of thrombus.File:IPlab4AtheromatousEmboli2IPLab4AtheromatousEmboli2.jpg|This is a closer view of the luminal surface of the aorta from the previous image. The rough, ulcerated surface and the thrombotic material can be easily seen in this image.File:IPlab4AtheromatousEmboli3IPLab4AtheromatousEmboli3.jpg|This is a low-power photomicrograph of kidney tissue. Several blood vessels can be identified at the corticomedullary junction (arrows). File:IPlab4AtheromatousEmboli4IPLab4AtheromatousEmboli4.jpg|This higher-power photomicrograph of one of the arcuate arteries reveals a cholesterol embolus. Note the needle-shaped space (arrow) within the lumen of this artery (arrow) which represents the space occupied by the cholesterol crystal that was dissolved away during histologic processing.File:IPlab4AtheromatousEmboli5IPLab4AtheromatousEmboli5.jpg|This is another view of this vessel with an atherosclerotic embolus. Note the cholesterol clefts (1) and thrombotic material (2) that occlude this artery. File:IPlab4AtheromatousEmboli6IPLab4AtheromatousEmboli6.jpg|A mesenteric artery also had an atherosclerotic embolus. Again note the cholesterol clefts and thrombotic material that occlude this artery.
