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 6 4.6 % ,其中毛刺样肿块影占 2 7.0 % ,边缘模糊肿块影占 2 4.2 % ,分叶状占 10 .7% ,类圆形肿块影占 2 .8%。 40例(2 2 .5 % )乳腺癌显示簇样钙化。 41～ 5 0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。
Objective To investigate the features of mammographic X-ray imaging of breast cancer and its pathological basis in order to improve the diagnostic level. Methods The X-ray findings of 178 cases of breast cancer confirmed by surgery and pathology were summarized. Results The site of the disease was more often seen in the outer quadrant, accounting for 43.8%. 178 cases of breast cancer showed X-ray films with a mass of 64.6 %, of which spur-like mass shadows accounted for 27.0 %, marginal mass shadows accounted for 2 4.2 %, lobulated shape accounted for 10.7%, similar to round mass shadows. It accounts for 2.8%. Forty patients (22.5%) showed cluster-like calcification. 41 to 50 years old were the high-onset breast cancer group, accounting for 35.4%. The incidence of invasive ductal cancer was the highest, accounting for 44.9%, followed by cancer alone, accounting for 34.3%. Conclusions1 In addition to characterization of breast cancer with characteristic signs: mass shadow and cluster-like calcification, attention should also be paid to the indirect signs of focal shadowing and local structural disorder. 2 The pathological basis of breast cancer is different, resulting in different types of X-ray findings.
