“…The Brazilian radiological literature has recently been preoccupied with the relevant role of imaging methods in the improvement of breast diseases diagnosis (22)(23)(24)(25)(26)(27)(28)(29)(30)(31) . With the consolidation of data at SIS-MAMA, the evaluation of indicators based on national standards and proposed targets became possible by means of a contextualized observation of mammographic results reported by the SUS' diagnostic centers, allowing greater swiftness in the processing of data necessary for the planning and implementation of public health policies and better allocation of resources in this area (13) .…”

Objective To evaluate the performance of diagnostic centers in the classification of mammography reports from an opportunistic screening undertaken by the Brazilian public health system (SUS) in the municipality of Goiânia, GO, Brazil in 2010. Materials and Methods The present ecological study analyzed data reported to the Sistema de Informação do Controle do Câncer de Mama (SISMAMA) (Breast Cancer Management Information System) by diagnostic centers involved in the mammographic screening developed by the SUS. Based on the frequency of mammograms per BI-RADS® category and on the limits established for the present study, the authors have calculated the rate of conformity for each diagnostic center. Diagnostic centers with equal rates of conformity were considered as having equal performance. Results Fifteen diagnostic centers performed mammographic studies for SUS and reported 31,198 screening mammograms. The performance of the diagnostic centers concerning BI-RADS classification has demonstrated that none of them was in conformity for all categories, one center presented conformity in five categories, two centers, in four categories, three centers, in three categories, two centers, in two categories, four centers, in one category, and three centers with no conformity. Conclusion The results of the present study demonstrate unevenness in the diagnostic centers performance in the classification of mammograms reported to SISMAMA from the opportunistic screening undertaken by SUS.

RESUMENEl carcinoma ductal in situ (CDIS) se encuentra en un grupo heterogéneo de tumores, cuyo diagnóstico se ha visto incrementado con el uso de la mamografía como método de cribado. El sistema de clasificación de Van Nuys, que se basa principalmente en el grado nuclear histológico y la presencia de necrosis, es el sistema más reproducible para la clasificación histopatológica. La anomalía más común que se observa en la mamografía son las microcalcificaciones, coexistiendo con otras lesiones como masas y distorsión arquitectural, que representan lesiones de bajo grado. El diagnóstico inicial debe realizarse mediante anamnesis y examen físico detallado que permita realizar una aproximación a las características morfoestructurales de la lesión, para posteriormente llegar a un acercamiento imagenológico y dinámico mediante resonancia magnética (RM), complementada con técnicas de inmunohistoquímica que caractericen el tumor. La presencia de distribución segmentaria morfológica es típico de malignidad (CDIS). La cinética de las lesiones en el estudio dinámico de la RM varía, siendo patognomónico de CDIS el patrón de washout en la fase de reforzamiento tardío. Sin embargo, el patrón dinámico parece estar correlacionado con los hallazgos mamográficos. Los hallazgos de RM y TC multidetector pueden ser útiles en combinación con la RM de mama para el mapeo preoperatorio. Sin embargo, existen técnicas complementarias como la espectroscopía y la difusión ponderada que mejoran la especificidad de la RM y tienen utilidad en la predicción de respuesta a la quimioterapia adyuvante. Estas aplicaciones futuras podrán mejorar la capacidad de diagnóstico oportuno y opciones de tratamiento.Palabras clave: Carcinoma ductal in situ; microcalcificaciones; mamografía; resonancia magnética; patología. Current issues in the diagnosis of ductal carcinoma in situ: a radiopathological correlation ABSTRACTDuctal carcinoma in situ (DCIS) falls into a heterogeneous group of tumors, whose diagnosis has increased with the use of mammography as screening method. The Van Nuys Prognostic Index, mainly based on histological nuclear grade and presence of necrosis, is the most reproducible histopathological classification system. The most common abnormality observed during a mammography are microcalcifications, which coexist with other lesions such as masses and architectural distortion, and represent low-grade lesions. The initial diagnosis should be performed by anamnesis and a detailed physical examination to help determine the morphostructural characteristics of the lesion. Then an imaging and dynamic approach should be achieved by magnetic resonance imaging (MRI) complemented by immunohistochemistry to characterize the tumor. The presence of morphological segmental distribution is typical of malignancy (DCIS). The kinetics of the lesions using a dynamic MRI varies, with the washout and late enhancement pattern being pathognomonic for DCIS. However, the dynamic pattern seems to be correlated with mammographic findings. Multidetector CT and MRI fi...

“…In such a context, mammography, ultrasonography and magnetic resonance imaging represent fundamental tools in the attempt to recognize findings not only suggesting the diagnosis of MMC, but also helping to differentiate between the two his-tological types of the neoplasm directly related to different prognostic factors (11,(13)(14)(15) .…”

Mucinous carcinoma of the breast: iconographic essay with histopathological correlation

et al. 2013

View full text Add to dashboard Cite

The present essay is aimed at describing the most characteristic imaging findings of mucinous carcinoma of the breast, with emphasis on the patterns related to better prognosis. The authors selected cases of mucinous carcinoma of the breast whose images were available, highlighting the imaging findings suggestive of this subtype of breast cancer, either at mammography, ultrasonography or magnetic resonance imaging.
