Caseous mitral annular calcifications: Multimodality imaging characteristics

Figure 6 In a different patient, not described herein, the more characteristic appearance of mitral annular calcifications is demonstrated (arrows). These are seen on the P-A view (A), with window and level settings adjusted to better visualize the mitral annular calcifications. The typical C-shape of the mitral annular calcifications is also demonstrated on the lateral view (B) and on a non-contrast CT image through the level of the heart (C) (kVp = 120, mAs = 212, DFOV = 310 mm). Note the difference between the chunky, coarse, C-shaped calcifications seen in this patient and the ovoid, mass-like calcifications with liquefied calcium that we describe.
