Abstract：Acute ischemic stroke is less likely to be caused by carotid artery occlusion related to compression from the hyoid bone.This case report described a patient with acute ischemic stroke due to hyoid bone compression-induced carotid artery occlusion who presented with speech disorder and hemiplegia,without atherosclerotic factors in the past and with exercise history.Head CT angiography showed no atherosclerosis changes in regions outside the offending vessel.Considering the anatomical relationship between hyoid bone and carotid artery,the most reasonable mechanism might be owed to repetitive mechanical compression from ipsilateral greater horn of hyoid bone.It induced endothelial damage to the carotid artery,leading to occlusion and ischemic stroke consequently.It is extremely rare in patients with ischemic stroke.Accordingly,based on the literature review,this study was conducted to explore clinical and imaging manifestations,pathogenesis,diagnosis,and treatment of this special clinical manifestation.
