乳腺错构瘤的X线诊断(附35例报告)

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。

X-Ray Diagnosis of Breast Hamartoma (a Report of 35 Cases)

Objective:To discuss the X-ray diagnostic features of breast hamartoma.Methods:35 pathologically testified cases of breast hamartoma were retrospectively analyzed.Results:In our collection of 35 cases of hamartoma,18 were mixed,8 were low and 9 were high in density;the size of the tumor masses was presented as follows:5 masses with a diameter of smaller than or equal 2.0cm,13 masses with a diameter of 2.1~4.0cm and 17 masses with a diameter of larger than 4.0cm.Tumor masses with clear contour in 28 cases were found,while the ones with blurred rims in 7 cases were demonstrated.Conclusion:The proportion of tumor components (the proportion of tumor elements,such as fat,glands,fibrous tissue) played an important role on the X-ray manifestations of breast hamartoma.
