A 72-year-old man with end-stage renal disease and who was on dialysis was admitted with fever and chills. Two years previously, he had been diagnosed with caseous calcification of the mitral annulus (CCMA). Blood cultures revealed Staphylococcus aureus, and echocardiography revealed vegetation attached to the CCMA lesion, progressing to both the anterior and posterior annulus. Infective endocarditis (IE) was diagnosed and antibiotic (ampicillin) treatment was initiated. Emergent mitral valve replacement was performed after the occurrence of multiple cerebral infarctions. During surgery, we identified vegetation attached to the CCMA lesion. After surgery, the patient showed a good recovery and was discharged. This case demonstrates that IE can be complicated with CCMA.
