Fig 1. A 68-year-old man with TIA. Axial CTA source image (A) and MIP (B) illustrate an ulcerated plaque with a severe stenosis in the right ICA (yellow arrow). Axial head CT scan (C) demonstrates ischemic lesions in the anterior limb of the left internal capsule. On the surgical specimen (D), the ulceration is clearly visible (D). US was negative for ulceration in this case.

Fig 2. A 71-year-old man with persistent monocular visual loss. Axial scan CTA source image (A), MPR (B), SSD (C), MIP (D), and US-ECD (E) show an irregular ulcerated plaque with moderate stenosis of the ICA. The ulcer is 4 mm and proximal to the point of maximum stenosis (yellow arrows). US was positive for ulceration in this case.
