Histological Evidence of Artery to Artery Embolism from Calcified Atherosclerotic Plaque of Carotid Artery

Artery to artery embolism is one of the main causes of cerebral infarction, and it can originate from many locations. Here we report a case of cerebral infarction in which calcified cerebral emboli were detected in brain computed tomography (CT). The calcified emboli were thought to originate from a carotid plaque that showed calcification and ulceration. We present histologic and micro-CT findings of a carotid plaque as a source of artery to artery embolism.
