What is architectural distortion in mammography?

Architectural distortion is a finding where the normal arrangement of breast tissue is pulled or distorted without there being a discrete lump. On a mammogram you’ll see lines or strands of tissue that seem to converge toward or radiate from a point, giving an irregular pattern rather than a clear, round mass. This is important because cancer can cause tissue to retract and distort the surrounding architecture even without a defined mass, though benign changes from scarring or radial scars can produce similar appearances. It’s different from motion artifact, which is image blur from movement, and from a defined mass or normal density changes, which don’t show this kind of directional distortion.
