Fig 1. A 71-year-old man with persistent monocular visual loss. VR (A, B), MIP (C), and axial scans (D) show a severe and irregular ulcerated plaque of the internal carotid artery (ICA). In the left ICA, proximal to the point of maximum stenosis (60% NASCET), is clearly depicted an ulceration of 2 mm (red arrows). In the VR images, A is set without contrast media histogram and B is set with contrast media histogram. In C, there is visible hook morphology (ICA, blue arrow).
