【摘要】：目的:探讨三阴性乳腺癌(TNBC)钼靶X线和超声影像特征。方法:回顾性分析54例TNBC患者的钼靶X线和超声影像资料。结果:TNBC肿瘤组织学分级高,在钼靶X线上常表现为肿块(69.8%),很少表现为肿块伴钙化(15.1%)、单纯钙化(1.9%)、局限性非对称致密(9.4%)或结构扭曲(3.8%)。肿块形状主要为圆形或椭圆形(62.2%),很少表现为不规则形(17.8%)。肿块常为清晰边缘(35.6%),毛刺边缘(11.1%)少见。在超声检查中,TNBC主要表现为肿块(87.0%),很少表现肿块伴钙化(9.3%)、单纯钙化(0%)或结构扭曲(3.7%)。肿块形状主要为圆形或椭圆形(51.9%),其次是不规则形(48.1%)。肿块常为清晰边缘(48.1%),毛刺边缘(5.8%)少见。肿块内部回声以低回声和混杂回声为主,肿块后方回声衰减少见,弹性评分多为4或5。结论:TNBC钼靶X线和超声表现更倾向于良性肿瘤的特点,了解其影像特征有助于提高TNBC的诊断水平。
[Abstract]:Objective: to investigate the characteristics of (TNBC) mammography and ultrasound in triple negative breast cancer. Methods: the mammography and ultrasound images of 54 patients with TNBC were analyzed retrospectively. Results: the histologic grade of TNBC tumor was high. On mammography, the tumor was often shown as mass (69.8%), rarely with calcification (15.1%), and only with calcification (1.9%). Localized asymmetric densification (9.4%) or structural distortion (3.8%). The shape of the mass was mainly round or oval (62.2%), and rarely irregular (17.8%). The clear margin (35.6%) and the burr margin (11.1%) were rare. In ultrasonic examination, the main features of TNBC were mass (87.0%), mass with calcification (9.3%), simple calcification (0%) or structural distortion (3.7%). The shape of the mass was mainly round or ellipse (51.9%), followed by irregular shape (48.1%). The clear margin (48.1%) and the bristle margin (5.8%) were rare. The internal echo of the mass was mainly low echo and mixed echo, the attenuation of the back echo was rare, and the elastic score was 4 or 5. Conclusion: TNBC mammography and ultrasound findings are more inclined to the characteristics of benign tumors, and understanding the imaging features is helpful to improve the diagnostic level of TNBC.
