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.

This case highlights a rare yet clinically significant complication of caseous calcification of the mitral annulus (CCMA), wherein three-dimensional transesophageal echocardiography clearly delineated a left ventricular-to-left atrial fistula secondary to CCMA rupture, resulting in hemolytic anemia.

Caseous mitral annular calcification (CMAC), a rare variant of mitral annular calcification (MAC), predominantly affects older adults. CMAC represents a very small fraction of MAC, and it features a necrotic core with peripheral calcifications, mimicking neoplasms. Multimodal imaging is essential for diagnosis.

Mitral annular calcification (MAC) is a common finding, especially among the elderly or patients undergoing haemodialysis. Caseous calcification of the mitral annulus (CCMA) is a rare MAC variant with liquefied material at the calcified annulus. Surgical management of CCMA often involves wide excision and debridement, increasing the risk of perioperative stroke.
