目的:总结32例非肿块型乳腺癌的数字化钼靶X线表现,提高对此类乳腺癌的诊断率,减少漏误诊。方法:对32例经手术病理证实乳腺癌的非肿块性钼靶X线征象进行综合分析。结果:32例乳腺癌中,各种微钙化15例,占46.9%,结构不良扭曲7例,占21.9%,局限性浸润致密影6例,占18.8%,乳腺导管造影示导管中断破坏,充缺4例,占12.5%。其它如:腋窝淋巴结肿大,血管异常,大导管相,局部皮肤及皮下脂肪层的改变等征象可合并存在。结论:非肿块型乳腺癌的X线表现多样化且不典型,极易造成漏误诊,充分认识和重视其影像特点,不断积累经验,提高早期诊断率。 Objective: To summarize the digital mammography manifestations of 32 cases of non-mass breast cancer, to improve the diagnosis rate of such breast cancer and to reduce the misdiagnosis. Methods: 32 cases of non-tumorous mammography confirmed by pathology and pathology were analyzed comprehensively. Results: In 32 cases of breast cancer, there were 15 cases (46.9%) with various types of microcalcifications, 7 cases (21.9%) with structural distortions, 6 cases (18.8%) with localized infiltration and dense shadow, In 4 cases, accounting for 12.5%. Others such as: axillary lymph nodes, vascular abnormalities, large duct phase, local skin and subcutaneous fat layer changes and other signs can be combined existence. Conclusion: X - ray manifestations of non - mass breast cancer are diverse and atypical, which can easily lead to misdiagnosis, fully understand and pay attention to its imaging features, accumulate experience and improve early diagnosis rate.
