Plaque rupture. Plaque rupture is defined as a presence of fibrous-cap discontinuity (arrows) and a cavity formation (*) in the plaque. Ruptured plaques usually have an extensive lipid core and a thin fibrous cap. The fibrous cap is the thinnest at the site of rupture, and the plaque cavity indicates loss of lipid core due to rupture.
