Evaluation of causal heart diseases in cardioembolic stroke by cardiac computed tomography

Figure 15  Caseous mitral annular calcification. A and B: Apical four chamber view (A) and parasternal short axis view (B) of transthoracic echocardiography show irregularly shaped calcific mass attached to mitral annulus adjacent to posterior mitral valve leaflet (arrows); C–F: Cardiac computed tomography (CCT) images with (C, D) and without (E, F) contrast medium. Horizontal long axis (C, E) and short axis (D, F) reformatted CCT images show a centrally hypodense mass with irregular calcified borders attached to mitral annulus adjacent to posterior mitral valve leaflet (arrows).
