乳腺纤维腺瘤的钼靶X线分析

Analysis of mammography on breast fibroadenoma

目的分析乳腺纤维腺瘤的特征性钼靶X线征象,以提高对本病的认识。方法回顾性分析经手术病理证实的70例乳腺纤维腺瘤的钼靶X线影像,所有病例术前均拍摄乳腺内外斜位像和头尾位像。结果本组70例纤维腺瘤中,钼靶X线片可显示62例,74个病灶,其中左乳36个病灶,右乳38个病灶。病灶形态圆形、类圆形60个,占81%,46个病灶边界清楚锐利,14个边界部分清楚,4个边界不清。周围有"包膜感征"40个,8例未能显示病灶。结论乳腺纤维腺瘤的特征性X线征象很重要,乳腺X线摄影术是诊断乳腺纤维腺瘤的良好方法。

Objective To study the imaging characteristics of breast fibroadenoma on mammograms. Methods Mammography of 70 patients with breast fibroadenoma confirmed by pathology were analyzed retrospectively. All patients took breast X-ray of mediolateral oblique projection and craniocaudal projection before operation. Results In 70 cases with fibroadenoma, mammography revealed 74 foci （36 left breast, 38 right breast） of 62 cases, and failed to reveal lesions in 8 cases. The shape of the lesions was round or round-like lesion in 60（81%）. The border was well-defined in 46 masses, partly well-outlined in 14 and ill-defined in 4. ＂Membranoid sign＂ can be seen in 40 cases. Conclusion Typical X-ray findings of breast fibroadenoma is very important, mammography is a good method of choice in diagnosis of fibroadenoma.
