Big mitral annular calcification: a case report of a dynamic liquefaction necrosis as a potential source of embolism.

A clear diagnosis and quantitative assessment of dynamic processes, such as cMAC, are made possible by performing CMR with multi-parametric tissue characterization. Dynamic changes in cMAC may have serious clinical implications, such as mitral regurgitation or systemic embolization. Among cardiac tumours, thrombus and abscess, cMAC should be included in the differential diagnosis of an intracardiac mass of the posterior mitral annulus in order to avoid further inappropriate diagnostic interventions.
