Abstract
To date, there have been only 15 reported cases of bilateral absence of the internal carotid artery. The authors describe a 70-year-old male with bilateral absence of the internal carotid artery and cerebral infarction. He was hospitalized because of a right sensory disturbance. Bilateral retrograde brachial angiography demonstrated filling of the right and left anterior and middle cerebral arteries by the dilated posterior communicating arteries. Neither bony carotid canal could be demonstrated by conventional computed tomography, including scanning of the petrous portion of the temporal bone. These neuroradiological findings confirmed the absence of the carotid arteries.
