Answer

The prevalence of embolization appears to be the same for both types of disease. The most common areas of deposition include the coronary arteries, kidneys, brain, and spleen. Infarction at the site of embolization is common; abscess formation is not. Cerebral emboli occur in 33% of patients. The middle cerebral artery is involved most often.

Other neurological embolic damage includes cranial nerve palsies, cerebritis, and mycotic aneurysms caused by weakening of the vessel walls and produced by embolization to the vasa vasorum. Mycotic aneurysms may occur in the abdominal aorta and the splenic, coronary, and pulmonary arteries.
