Whitfield Lewis Warns of Unstable Aortic Arch Plaque as Rare Source of Embolic Stroke

Whitfield Lewis, Vascular Neurologist, Clinical Assistant Professor at UPMC Altoona, posted on X:

”Great job. Rarely, a large unstable plaque (causing thrombus formation) in the aortic arch can mimic a cardioembolic stroke. That’s why I posted a picture of the arch. Don’t forget to pay attention to the arch when you see a clear pattern of embolic stroke in b/l hemisphere, suggesting a central origin. Attached is a pic of an unstable aortic arch plaque with associated thrombus, recognize it.”
