architectural distortion
Mammographic finding showing disruption of normal breast tissue pattern without visible mass or calcifications.
Full Definition
Architectural distortion represents a focal disruption of the normal breast parenchymal pattern visible on mammography, characterized by spiculation or retraction without an associated mass or calcification cluster. This finding can indicate the presence of invasive carcinoma, particularly infiltrating lobular carcinoma, or may result from benign conditions such as surgical scarring or radial scars. Architectural distortion requires careful evaluation and often necessitates additional imaging or tissue sampling for definitive diagnosis.
Usage
Usage note: Use as a specific radiological term; avoid confusion with general breast asymmetry or mass descriptions.
