Caseous calcification is a rare form of mitral annular calcification. Echocardiography reveals an echodense mass in the inferior mitral annulus with smooth borders and an echolucent inner core. We present a case where caseous calcification of the mitral annulus caused severe mitral regurgitation, atrial fibrillation and heart failure. Transthoracic echocardiography, transesophageal echocardiography, cardiac mag- netic resonance and computed tomography were performed and ensured the diagnosis. The mass was surgically removed and a prosthetic valve was implanted. We conclude that caseous calcification of the mitral annulus should be considered not only in the differential diagnosis of cardiac masses but also in the background of mitral regurgitation, atrial fibrillation and heart failure. This case also represents the usefulness of multimodal imaging in identifying cardiac masses.
