目的:探讨超声对小体积(直径<5cm)乳腺叶状肿瘤和纤维腺瘤鉴别诊断的价值。方法:回顾性分析经病理证实、直径均<5cm的12例乳腺叶状肿瘤和96例纤维腺瘤患者的超声表现。结果:囊性变、Ⅱ级和Ⅲ级血流信号(根据Adler半定量法分级)在2组患者中的检出率差异有统计学意义(P<0.05)。其中囊性变和Ⅲ级血流信号诊断的特异性和准确性较高,特异性均为99.0%,准确性分别为91.7%和90.7%。结论:囊性变和Ⅲ级血流信号是鉴别诊断直径<5cm的乳腺叶状肿瘤和纤维腺瘤的重要指标。Ⅱ级血流信号在二者中存在较大重叠,可作为鉴别诊断的参考指标。
Objective: To investigate the value of ultrasonography in the differential diagnosis of small volume (diameter <5cm) breast phyllodes tumor and fibroadenoma. Methods: The ultrasound findings of 12 cases of breast phyllodes tumor and 96 cases of fibroadenoma confirmed by pathology and with diameter <5cm were retrospectively analyzed. Results: The detection rates of cystic changes, grade II and grade III blood flow signals (classified according to Adler’s semi-quantitative method) were statistically different between the two groups (P <0.05). Among them, the specificity and accuracy of cystic degeneration and grade III blood flow signal diagnosis were high, with the specificity of 99.0% and the accuracy of 91.7% and 90.7% respectively. Conclusion: Cystic changes and grade Ⅲ blood flow signals are important indexes in the differential diagnosis of breast phyllodes tumor and fibroadenoma with diameter <5cm. Ⅱ grade blood flow signal in the two there is a large overlap, can be used as a differential diagnosis of reference indicators.
