Patient with recurrent right hemispheric transient ischemic attacks. a Axial CTA image demonstrates a web (arrow) of the right carotid bulb which has the appearance of a septum on axial images. b Coronal reconstructed image of the CTA shows the web as a shelf-like projection into the carotid bulb (arrow). c This is also demonstrated on the lateral projection right carotid angiogram (arrow). d Post-stenting angiogram shows resolution of the web with a patent right internal carotid artery.
