Figure 7. Non-contrast-enhanced computed tomography (CT) with sagittal reconstruction demonstrating caseous calcification of the mitral annulus (CCMA). The CCMA (arrow) is localized in the atrioventricular groove, and it is a hyperdense, well-defined, round mass, with a couple of internal calcification areas and 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 values ranging from 723 HU to 1245 HU. The internal calcification areas of the lesion had attenuation values ranging from 1124 HU to 1169 HU.
