Caseous Calcification of the Mitral Annulus: Mimicking A Cardiac Mass

Mitral annulus calcification is a common incidental finding in echocardiography examination of predisposed populations. On the other hand, caseous calcification of the mitral annulus is a rare variant that challenges the physician to differentiate it from different causes of cardiac masses. We describe a case of incidentally discovered caseous calcification confirmed with CT cardiac and cardiac magnetic resonance. LEARNING POINTS: Caseous calcification of the mitral annulus is a rare condition. An important differential diagnosis is cardiac tumours and myocardial abscesses. Cardiac computed tomography and cardiac magnetic resonance imaging are important in confirming the diagnosis, and assessing the extent and location of annular calcium.
