摘要
目的分析135例乳腺癌X线表现与病理改变的关系,以提高诊断水平。方法将135例乳腺癌的X线征象作回顾性分析。结果发病部位以乳腺外上象限多见占41.5%,其中非浸润乳腺癌5例,早期浸润性癌23例,特殊型浸润性乳腺癌20例,非特殊型浸润性乳腺癌87例。135例中X线显示肿块占77.0%,其中不规则或分叶肿块占40.0%,毛刺状肿块46.7%。显示恶性钙化56例(41.5%)。X线表现为三型:肿块型、浸润型、钙化型。结论乳腺癌的影像多以肿块型为主,呈高密度、形态不规则、边缘分叶、星芒壮或毛刺状。泥沙样微细钙化为诊断乳腺癌的重要依据。X线摄影是诊断和鉴别诊断乳腺癌的最有价值的方法。影像学表现与乳房触诊密切结合可进一步提高诊断率。
Objective To investigate the relationship between the X-ray findings and the pathophysiological changes in 135 cases with breast carcinoma in order to increase the dingnostic accuracy.Methods The mammographic manifestation of 135 patients with breast carcinoma were analyzed retrospectively.Results The outer upper quadrant to the breast was the major position of lesion (41.5 %).In the 135 cases,5 cases were non-infiltrative carcinoma;23 cases were early infiltrative carcinoma;20 cases were specific infiltrative carcinoma;87 cases were non-specific infiltrative carcinoma.The mass pattern was the main type of lesion in 135 cases.It made up 77.0 % in which the irregular contour and/or foliar mass was 40.0%,the spiculate mass was 46.7 %.56 cases had malignant calcifications(41.5 %).The X-ray features were summarized as follow:mass,infiltration,calcification.Conclusion The roentgenologic mass were the main X-ray findings.The features of these mass are highdense central area,irregular contour and numerous fine spicula radiating out from mass.These characteristics represent typical mammographic feature of malignancy.Microcalcification is a very important X-ray sign for diagnosing breast cancer.Mammography has of great value in diagnosing and differentiating breast carcinoma.X-ray images closely combined with breast touching examination can improve the diagnostic accuracy.
