Which of the following are associated with caseous annular calcification?

Which of the following are associated with caseous annular calcification?

• A. Calcium metabolism abnormalities
• B. Chronic renal failure
• C. Both calcium metabolism abnormalities and chronic renal failure
• D. Neither calcium metabolism abnormalities nor chronic renal failure

Answer: (C)

Caseous annular calcification is a variant of mitral annulus calcification where the calcified rim contains a central, liquefied (caseous) material. It tends to occur in people with systemic disturbances in calcium-phosphate metabolism. Chronic kidney disease often disrupts calcium and phosphate balance and can cause secondary hyperparathyroidism, which promotes calcification in cardiovascular structures including the mitral annulus. Because of these intertwined metabolic changes, caseous annular calcification is associated with both calcium metabolism abnormalities and chronic renal failure. The combination of these factors best explains why both are linked to this condition.
