Fig 2.

A 67-year-old-male patient who underwent right carotid endarterectomy. The histopathologic figure (a) shows an intact and thick fibrous cap (FC) separating the necrotic core (N) from the lumen (L). In panel (b), the computed tomography angiography (CTA) axial slice is shown, and the white arrows show the presence of a mixed plaque (open white arrow) with thin calcifications (open arrow). The ultrasound image (c) obtained at the same day of the CTA confirm the presence of a mild carotid artery plaque with focal area of hyperechogenicity related to the presence of calcium (open white arrow).
