Abstract

Embolic stroke of undetermined source (ESUS) is not uncommon in young patients. Here, we describe two cases of stroke from an unusual aetiology; cerebral embolization from carotid artery injury presumed secondary to hyoid bone impingement. Both patients demonstrated angiographic evidence of hyoid bone impingement. Following resection of the greater cornu of the hyoid bone, neither patient had further strokes.

Keywords: Carotid-hyoid syndrome; Embolic stroke; Hyoid bone.
