Imaging of Mobile Emboligenic Calcified Amorphous Tumor in Mitral Annular Caseous Calcification.

ABSTRACT:

Background

Caseous calcification of the mitral annulus (CCMA), a rare variant of mitral annular calcification, is occasionally associated with calcified amorphous tumors (CATs). These distinctive lesions are poorly documented, particularly regarding their potential for mobility and embolism.

Case summary

A 73-year-old woman presented with acute left-sided hemiparesis and dysarthria. Serial echocardiography revealed CCMA-associated CAT with characteristic hypoechogenic appearance and peripheral calcification, demonstrating significant mobility with embolic events. The patient underwent urgent tumor resection, mitral valve replacement, and coronary artery bypass grafting, resulting in full recovery.

Discussion

This case uniquely captures the mobility and embolic risk of
