title: [Architectural distortion and diagnostic difficulties].
abstract: Identification of architectural distortion requires a good practice of mammography. Prevalence is estimated at 6% of detected abnormalities in screening programs. Under this denomination are gathered focal architectural distortion with predictive positive value (PPV) of 10% and stellate images without central densification, which are more suspicious (PPV 50%). In order to establish a diagnosis, false images must be eliminated by other views. Minimal architectural distortion have to be investigated by other techniques (sonography, MRI percutaneous biopsy) in order to define the best strategy for further management. Stellate images suggestive of radial scars must be surgically removed. The relationships between radial scars and tubular carcinoma are discussed. A particular attention is required for post traumatic or post surgical scars if it exist a high risk of local recurrence or controlateral carcinoma specially after conservative or oncoplastic surgery.
