目的:探讨乳腺错构瘤的X线诊断及意义。方法:回顾性分析35例经手术病理证实的乳腺错构瘤患者的乳腺X线资料,并与手术病理对比分析。结果:35例乳腺错构瘤在X线片上以脂肪组织与纤维腺体组织不同比例混合,呈混合型密度的肿块影有18例,以脂肪组织为主呈脂肪型低密度的肿块影有8例,以纤维腺体组织为主呈致密型密度的肿块影有9例;肿块影大小分布,≤2.1cm有5例,在2.1~4.0cm的有13例,>4.0cm有17例;肿块影边缘清晰的有28例,模糊及较清晰共有7例。结论:乳腺错构瘤的X线表现与其病灶内低密度的脂肪组织及高密度的腺体组织、纤维组织所占的比例有关,其中混杂密度是其特异性的X线表现。
Objective: To investigate the X-ray diagnosis and significance of hamartoma. Methods: The mammographic data of 35 cases of breast hamartoma confirmed by surgery and pathology were retrospectively analyzed, and compared with the surgical pathology. Results: Thirty-five cases of breast hamartoma were mixed with different proportions of adipose tissue and fibro-glandular tissue on X-ray film. There were 18 cases of mixed density mass with 18 cases of adipose-type low-density mass with 8 cases For example, fibroadenocarcinoma mainly dense mass density of the mass in 9 cases; mass shadow distribution, ≤ 2.1cm in 5 cases, 2.1 ~ 4.0cm in 13 cases,> 4.0cm in 17 cases; mass Shadow edge of the clear in 28 cases, fuzzy and more clearly a total of 7 cases. Conclusion: X-ray findings of breast hamartoma are related to the density of low-density adipose tissue and high-density glandular tissue and fibrous tissue in the lesion. The mixed density is the specific X-ray manifestation.
