Caseous Annular Calcification is best described as which of the following?

• A. Common variant of annular calcification
• B. Rare variant of annular calcification
• C. A calcification of the aortic annulus
• D. A growth on the leaflets

Answer: (B)

Caseous annular calcification is best understood as a rare variant of annular calcification, specifically involving the mitral annulus. The term “caseous” describes a central area of soft, cheese-like necrosis surrounded by a calcified shell. This sets it apart from the more common, solid annular calcification and explains why it can resemble a mass or vegetation on imaging. It is not a simple calcification of the aortic annulus, nor a growth on the valve leaflets, reinforcing why the correct description is that this is a rare form of annular calcification.
