Caseous calcification of the mitral annulus-associated calcified amorphous tumour with chronic inflammatory cardiomyopathy: a case report.

ABSTRACT:

Background

Calcified amorphous tumour (CAT) is a rare lesion that forms at various sites of the heart, including the mitral annulus. Since it is a systemic embolic source, it often requires resection. In contrast, caseous calcification of the mitral annulus (CCMA) usually receives conservative follow-up; however, it is sometimes resected to prevent embolism. Herein, we present a rare case of CCMA-associated CAT with chronic inflammatory cardiomyopathy and comprehensively consider the aetiology of CCMA-associated CAT.

Case summary

A 52-year-old man with end-stage renal failure requiring haemodialysis underwent annual follow-up echocardiography for aortic valvular dysfunction. Echocardiography revealed a well-defined 22 × 17-mm circular mass on the annulus of the posterior mit
