Liquefaction necrosis of mitral annulus calcification

Liquefaction necrosis of the mitral annulus is a rare form of peri‐annular calcification that the cardiologist must be able to differentiate from other cardiac masses. It classically looks like a round or semilunar hyperdense mass with a denser peripheral rim, located mainly in the posterior mitral annulus. The case we report here was diagnosed in a 78‐year‐old female patient who presented with an embolic cerebral vascular accident, which raises the question of its etiopathogenic responsibility. © 2014 Wiley Periodicals, Inc.
