A case of caseous calcification of the mitral annulus with mobile mass.

ABSTRACT: A 75-year-old woman had a 4-year history of hemodialysis and underwent aortic valve replacement for aortic valve stenosis one year previously. She was referred to our hospital to treat atrial fibrillation. Echocardiography at the initial visit incidentally revealed mitral annular calcification (MAC) involving the posterior mitral leaflet and mobile mass attached to this MAC. The high intensity echogenic mobile mass extended from the sub-valvular tissue to the papillary tendon. The differential diagnosis of this mass included a caseous calcification of the mitral annulus (CCMA), and intra-cardiac thrombus or tumor. Computed tomography imaging features were consistent with CCMA. Anticoagulation was administered for one month to rule out thrombus and to prevent systemic thromboembolism. The s
