钙化在不伴肿块乳腺肿瘤中的表现特点分析

Analysis of Mammographic Characteristics of Calcification in Breast Tumor Without Mass

目的探讨钙化在非肿块型乳腺肿瘤X线诊断中的意义,提高对非肿块型乳腺良、恶性肿瘤的鉴别诊断水平。方法回顾性分析2008年11月至2011年3月期间四川大学华西医院经病理检查证实的X线片未见肿块的90例乳腺肿瘤患者的临床资料,其中乳腺良性肿瘤55例,乳腺癌35例,观察并记录钙化的形态、分布、总数、位置及乳腺局限性不对称致密。结果①乳腺良性疾病钙化形态多粗大(31例),多以散在分布为主(35例),且钙化总数较少,较少伴有乳腺局限性不对称致密影(7例),较少伴有同侧腋窝淋巴结的改变(2例)。②乳腺癌的钙化多以细砂样钙化为主(32例),颗粒细小,但钙化大小不一致,形态各异,其钙化的分布多呈簇样分布(24例),且恶性钙化的总数较多,多伴有乳腺局限性不对称致密影(24例),伴有腋窝淋巴结改变(10例)。两者钙化的形态、分布及总数的差异均有统计学意义(P<0.05)。结论良、恶性乳腺肿瘤的钙化各有特征,在早期乳腺肿瘤的鉴别诊断中有着重要的临床意义。

Objective To investigate the X-ray diagnostic significance of calcification of the breast tumor without mass.Methods Mammograms of 90 cases of breast tumor without mass confirmed pathologically were retrospectively analyzed.There were 55 cases confirmed benign breast tumor,and the rest cases were breast cancer.The shape,distribution,total number,location of calcifications in the breast,and asymmetric dense of the breast were recorded and watched.Results ①The X-ray findings of calcification in benign breast tumors always presented as coarse granular（31）,scattered shape（35） with small number,less with the asymmetric dense of the breast（7）,and the change of side with axillary lymph node（2）.②Meanwhile,fine sand-like（32）,showing the cluster-like distribution（24） with larger number,with the asymmetric dense of the breast（24） and the change of side with axillary lymph node（10）.Both of the differences of the calcifications（the shape,the distribution,and the total number） were statistically significant（P0.05）.Conclusions The calcifications of benign and malignant breast tumors have their unique X-ray characteristics.And there is a great value in differentiating early benign and malignant breast tumor.
