ABSTRACT
Screening for breast cancer with conventional mammography (MG 2D) digital has known, well-documented limitations. The report false negatives screening in a range of 8-66% and depends on many factors, including: age, density, tumor type and misinterpretations of some mammographic findings. The architectural distortion (AD) is the third most common manifestation of non-palpable breast cancer and are often not visible in conventional mammography. A sample of cases, occur in asymptomatic patients attending screening study. Architectural distortions, detected in tomosynthesis (MG 3D), are documented. In the cases shown, AD in MG views, were not initially observed in conventional mammogram, or were only seen as asymmetry. In all patients complementary ultrasound they were performed to corroborate AD. The lesions showed a mean diameter of 10 mm (from 5-15 mm), with some findings associated as vascularity, acoustic shadow and echogenic halo. In patients in whom it was obtained histopathologic result showed that in cases where the AD was not presented in MG 2D, demonstrate carcinoma in situ. In cases of dense and heterogeneously dense breasts, where an asymmetry was presented in MG 2D, MG 3D showed DA, resulting in infiltrating carcinoma.REFERENCES
