Abstract
We report an 85-year-old woman with caseous calcification of mitral annulus (CCMA),
a rare variant of mitral annular calcification with caseous degeneration, in which
imaging findings were useful for elucidating the pathogenesis and diagnosis. Since
the CCMA is considered to be benign, it is important for clinicians to differentiate
CCMA from other cardiac masses using multi-modality imaging in order to avoid unnecessary
surgery. To the best of our knowledge, there is a paucity of literature regarding
cardiac magnetic resonance (CMR) parametric mapping, an emerging technique, for evaluating
CCMA. In the present case, by using multi-modality imaging including CMR parametric
mapping, we were able to characterize the abnormal structure at mitral annulus non-invasively,
and diagnosed the structure as CCMA. CMR with parametric mapping may have a role in
the identification and definition of cardiac masses including CCMA.
Learning objective
Caseous calcification of mitral annulus (CCMA) is a rare variant of mitral annular
calcification, but is not infrequently encountered in daily practice. Multi-modality
imaging including cardiac magnetic resonance is useful for the diagnosis of CCMA.
Differential diagnosis of cardiac masses at the mitral annulus including CCMA is important,
and clinicians need to know the multi-modality imaging findings related to CCMA.
