Carotid webs are an uncommon cause of recurrent ischaemic strokes. They are considered a form of fibromuscular dysplasia, possibly developmental in origin, with non-inflammatory and non-atherosclerotic features and a characteristic appearance on CT angiography. They have been described as a thin intraluminal filling defect along the posterior wall of the carotid bulb in oblique sagittal reformats and a septum on axial CT angiography. Here we summarize two cases of ischaemic strokes secondary to carotid webs with characteristic images. Detection and awareness of carotid webs and their imaging features among radiologists and physicians are important as it is associated with a high risk of recurrent cerebrovascular events.
