OBJECTIVE
The objective of our study was to identify characteristic features of invasive lobular carcinoma on mammography and ultrasound examinations.
MATERIALS AND METHODS
This is a retrospective multicenter study of women with biopsy-proven invasive lobular carcinoma. All patients had undergone diagnostic sonomammography. The imaging findings were identified by experienced breast imagers. Final surgical pathology results were used as the reference standard.
RESULTS
Thirty-two women ranging in age from 42 to 63 years old (mean age, 53 years), All had biopsy-proven invasive lobular carcinomas. Common features on mammogram included dense mass followed by architectural distortion; three cases showed breast asymmetry and one case was reported as normal. On ultrasound, common features included solid mass with spiculated margins, posterior shadowing, and perpendicular to the skin.
CONCLUSION
Although no specific features could be linked to invasive lobular carcinoma, care should be directed to subtle signs such as architectural distortion and breast asymmetry in order not to miss any lesions. The combination of mammographic and sonographic helps to decrease the relatively high false negative diagnosis of this type of breast cancer.
目的
本研究的目的是在乳腺 X 线摄影和超声检查中识别浸润性小叶癌的特征性表现。
材料和方法
这是一项经活检证实为浸润性小叶癌的女性回顾性多中心研究。所有患者均接受了诊断性超声乳腺检查。有经验的乳腺成像专家对影像学表现进行了识别。最终的手术病理结果被用作参考标准。
结果
32 名年龄在 42 至 63 岁之间（平均年龄 53 岁）的女性，均经活检证实为浸润性小叶癌。乳腺 X 线摄影的常见特征包括致密肿块伴结构扭曲；3 例表现为乳房不对称，1 例报告为正常。在超声检查中，常见特征包括有毛刺状边缘的实性肿块、后影和垂直于皮肤。
结论
尽管没有特定的特征可以与浸润性小叶癌相关联，但应注意细微的征象，如结构扭曲和乳房不对称，以免遗漏任何病变。乳腺 X 线摄影和超声检查的结合有助于降低这种类型乳腺癌相对较高的假阴性诊断率。
