CONCORDANCIA IMAGINOLOGICA-PATOLOGICA EN BIOPSIA CORE DE MAMA

Abstract: The purpose of this study was to determine the frequency, concordance and discordance of breast lesions during automated core biopsy . A US-guided 14 –gauge automated core needle biopsy was performed on 188 lesions. Only in 1 of 120 bening diagnosed cases imaging–histologic discordance was present. This lesion underwent surgical excision and the case was diagnosed as having carcinoma in situ, as a definitive histological diagnosis. Assessment of correlation between imaging studies and histologic findings, as well as determination of concordance, are required to minimize diagnostic errors. Key Words: Breast lesion, Core biopsy, Imaging-histologic concordance. Resumen: El proposito de nuestro estudio fue deter-minar la frecuencia, concordancias y discordancias de las lesiones mamarias. Se realizaron 188 biopsias core con aguja de 14G. Solo 1 de las 120 lesiones benignas diagnosticadas fue discordante; se recomendo escision quirurgica cuyo resultado definitivo demostro carcinoma in situ. Para minimizar errores diagnosticos, se requiere evaluar la correlacion entre las imagenes y el resultado histologico, ademas de establecer la concordancia.
