Figure 6. Non-contrast-enhanced computed tomography (CT) with axial reconstruction showing caseous calcification of the mitral annulus (CCMA). CCMA (arrow) is situated in the atrioventricular groove, and it is a hyperdense, well-defined, round mass, measuring 20×19×39 mm and having a couple of internal calcification areas and a partly calcified border. The attenuation value range of the central area of the lesion was from 410 HU to 650 HU. The edge of the mass had the attenuation value range from 723 HU to 1245 HU. The internal calcification areas of the lesion had attenuation values ranging from 1124 HU to 1169 HU.
