Key result
Caseous mitral valve calcification presents as a benign intracardiac mass requiring multimodality imaging for diagnosis.
Why the study?
Caseous calcification, a rare variant of mitral annular calcification, can mimic more sinister calcified cardiac masses and requires differentiation.
Case Report (n=1)
Caseous mitral annular calcification is a benign condition that can mimic sinister cardiac masses or lung tumors, highlighting the importance of multimodality imaging for accurate differentiation.
Caseous MAC should be considered in calcified cardiac masses to avoid misdiagnosis; leaves open standardized multimodality imaging protocols.
Mitral annular calcification (MAC) is a common condition of the mitral valve apparatus. A case involving caseous calcification, a rare variant of MAC is presented. This variant which has a benign course can present as an intracardiac mass and needs to be differentiated from more sinister causes of calcified cardiac masses such as tumor, abscess, and infective vegetation. Often, this requires multimodality imaging with echocardiography, computed tomography, and magnetic resonance imaging. Features of caseous calcification of the mitral valve on these imaging modalities are reviewed as the associations and clinical features.

Dingli et al. (2017) conducted a case report in Caseous mitral annular calcification (n=1). Multimodality imaging (echocardiography, computed tomography, and magnetic resonance imaging) was evaluated. Caseous calcification of the mitral valve is a rare, benign variant of mitral annular calcification that can present as an intracardiac mass requiring multimodality imaging for diagnosis.
