摘要:

目的:观察超声图像及造影特征对乳腺导管内癌(ductal carcinoma in situ of breast,DCIS)的早期诊断价值。方法:分析2015年7月至2019年3月本院收治的经穿刺活检或手术病理证实的25例DCIS患者的超声图像及造影特征资料。结果:常规高频超声检查DCIS检出率为68.0%(17/25),结合超声造影检查DCIS检出率为92.0%(23/25)。其中腺体增厚或结构紊乱型占8.0%(2/25),导管扩张型占16.0%(4/25),片状低回声型占56.0%(14/25),混合回声肿物型占20.0%(5/25)。DCIS的超声造影特征表现为高增强多见,增强后病灶形态多不规则,边界多不清晰,分布尚均及不均,大部分无充盈缺损,造影剂进入肿块的大小及范围多超过二维超声图像,周围见多条粗大的血管进入肿块。结论:DCIS具有一定的超声造影特征表现,结合超声图像与造影特征有助于提高诊断率。

Objective:To evaluate the early diagnostic value of characteristic of ultrasonography and contrast-enhanced ultrasound(CEUS) in ductal carcinoma in situ (DCIS) of breast. Methods:The characteristic of ultrasonography and contrast-enhanced ultrasound in 25 cases of pathologically-confirmed DCIS from 7, 2015 to 3,2019 in hospital were retrospectively analyzed. Results:By conventional ultrasound and contrast-enhanced ultrasound,diagnostic accuracy of breast cancer in situ were 68.0%(17/25),92.0%(23/25).The ultrasonic appearance were classified as four types:hyperplasia of mammary glands with leopard type 8.0% (2/25),ductal dilatation type 16.0% (4/25),flaky hypoecho type 56.0%(14/25),mixed echo mass type 20.0% (5/25). DCIS contrast-enhanced ultrasonography was characterized by high enhancement, irregular morphology, unclear boundary, uniform and uneven distribution, and most of them had no filling defect. The size and range of the contrast-agent entering the mass were exceeding the two-dimensional ultrasound image ranges, and many large vessels were seen around the mass. Conclusion:DCIS can be characterized by contrast-enhanced ultrasound. The combination of conventional ultrasound and contrast-enhanced ultrasound can help to improve the coincidence rate.
