To the editor: Mitral annular calcification (MAC) is a common echocardiographic iraage mostly seen in elderly women, found in almost 10% of the population over 50 years old. MAC describes a degenerative process of the mitral annulus, particularly involving the posterior mitral valve annulus. Caseous calcification of the mitral annulus (CCMA) is a rare variant of MAC, constituting 0.6% of all MAC cases. Herein we present a case of CCMA, which can be misdiagnosed as cyst, abscess or mass.
