Presentation transcript:

Case 1, a 45-year-old female with recurrent small strokes in the right middle cerebral artery. (A) Axial computed tomography angiography (CTA) images on admission demonstrate a subtle irregularity along the posterior margin of right internal carotid artery origin, a typical appearance for a carotid web. (B) Magnified image from Figure 1A further illustrates the triangular intraluminal band along the posterior margin of the right internal carotid artery. (C) Coronal reconstruction of the CTA and (D) digital subtraction angiogram exhibit the characteristic shelf-like filling defect at the level of the carotid bulb (arrows). Note the lack of significant stenosis (<50%). Case 1, a 45-year-old female with recurrent small strokes in the right middle cerebral artery.
