Microcalcificaciones BIRADS 4: Experiencia de 12 años

Abstract

Objective: To know the clinical and histological association in presence of microcalcifications BIRADS 4. Method: Retrospective analysis of 204 patients with microcalcifications BIRADS 4, under mastectomy in Barros Luco-Trudeau Hospital between January 1993 and December 2004. The patients were marked previously with metallic harpoon in zone of microcalcifications and later radiological control of the surgical piece. Results: The location of BIRADS 4 microcalcifications was the left breast in 52% (106 cases), right breast 42% (85 cases), and both 6% (13 cases). The deferred biopsy showed 17 cases with mammary cancer (8.3 %), fibrocystic condition 197 cases (96.6%), non atypical hyperplasia 49 cases (24%), atypical hyperplasia 17 cases (8.3%), duct ectasia 7 cases (3.4%), papillomatosis 6 cases (2.9%), chronic mastitis 4 cases (2%), fibroadenoma 4 cases (2%), galactophoritis 2 cases (1%) and fat necrosis 2 cases (1%). Conclusion: The BIRADS 4 microcalcifications constitute an important mammography finding to be associated with breast cancer and high risk injuries in a high percentage.
