Breast Composition

Architectural Distorsion

Assymetries: visible on only one projection, mostly caused by superimposition of normal breast tissue.

Focal asymmetry: Visible on two projections, hence a real finding rather than superposition.

This has to be differentiated from a mass. Global asymmetry: Consisting of an asymmetry over at least one quarter of the breast and is usually a normal variant.

Developing asymmetry: New, larger and more conspicuous than on a previous examination.

Calcifications
