乳腺癌的X线表现与病理对照分析(附178例报告)

目的 探讨乳腺癌的钼靶X线影像特点及其病理基础，以提高诊断水平。方法 总结了经手术病理证实的178例乳腺癌的X线表现。结果 发病部位在外上象限较多见，占43．8％。178例乳腺癌X线片显示为肿块影的占64．6％，其中毛刺样肿块影占27．0％，边缘模糊肿块影占24．2％，分叶状占10．7％ ，类圆形肿块影占2．8％。40例（22．5％）乳腺癌显示簇样钙化。41－50岁为乳腺癌高发年龄组，占35．4％。浸润性导管癌发病率最高，占44．9％，其次为单纯癌，占34．3％。结论 ①诊断乳腺癌除了重视特征性征象：肿块影和簇样钙化，还应重视小灶致密影，局部结构紊乱等间接征象。②乳腺癌的病理基础不同，导致了不同类型的X线表现。

Correlative Study of X-ray Image and Pathology in Breast Cancer

ObjectiveTo investigate the imaging features of the mammogram by molybdenum targets roentgenography and their pathologic bases in order to improve the diagnostic level of breast cancer. MethodsOne hundred and seventy-eight cases of breast cancer confirmed by operation and pathology were studied. ResultsThe out-upper quadrant of the breast was the major position of lesion(43.8%).The mass was the main type of lesion in 178 cases, it made up 64.6%, in which the specula mass was 27.0%, the dim border mass was 24.2%, the foliar mass was 10.7% and the round mass was 2.8%. 40 cases(22.5%) had clustered calcifications. There was a high incidence(35.4%) in the age group of 41～50 years. Infiltrating duct cancer was a high incidence(44.9%) and the secondary was simple cancer(34.3%). Conclusion ①Besides attaching importance to characteristic mass and clustered calcification in diagnosis, special attention should be payed to indirect signs such as small focus of increased density and focal architecture distortion. ②Different X-ray images of breast cancer were due to distinct pathology bases.
