提示：三阴性乳腺癌通常发生在年轻女性中，并且具有侵袭性。重要的是这种亚型的肿瘤要及早发现。我们研究了73个肿瘤的乳房X光检查，超声检查和MRI的外观，以确定他们显示在imaging.Patients和方法：从2009年7月至2010年12月，我们回顾性审查了乳房X光检查和超声图像的73个三阴性癌症。34例用彩色多普勒显示血管，17例用弹性成像评分。16例患者接受了MRI检查。这些不同的模式的放射学描述借鉴了BI-RADS词汇和categorisation.Results：在乳腺X线摄影，三阴性癌往往表现为一个圆形的肿块（59.3%）或椭圆形或分叶肿块（65%），与外切（15%），microlobulated（12.5%），模糊（55%）或偶尔毛刺边缘（15%）。在超声检查中，绝大多数这些癌症表现为肿块（92.8%），偶尔有后方声衰减（22.6%）。MRI比常规检查显示更多可疑图像，尤其是边缘强化（12个肿块中有8个）。放射学图像更容易表现为分叶状肿块，而超声检查中后部增强比衰减更常见，MRI发现边缘增强。
OBJECTIVES: Triple-negative breast cancers generally occur in young women and they have the potential to be aggressive. It is important for this subtype of tumour to be detected early. We studied the appearance of 73 tumours on mammography, sonography and MRI in order to determine what specific features they showed on imaging.PATIENTS AND METHODS: From July 2009 to December 2010, we retrospectively reviewed mammogram and sonogram images of 73 triple-negative cancers. Colour Doppler had been used to depict vascularisation in 34 cases and elastography score calculated in 17 cases. Sixteen patients had undergone MRI. The radiological description of these different modalities draws on the BI-RADS lexicon and categorisation.RESULTS: On mammography, triple-negative cancers often presented as a round mass (59.3%) or an oval or lobulated mass (65%), with circumscribed (15%), microlobulated (12.5%), indistinct (55%) or occasionally spiculated margins (15%). On sonography, the vast majority of these cancers appeared as masses (92.8%) with occasional posterior acoustic attenuation (22.6%). MRI showed more suspicious images than the standard examinations, notably rim-enhancement (eight out of 12 masses).CONCLUSION: . Radiological images appear as lobulated masses more readily, while on sonography posterior enhancement is shown more often than attenuation, and MRI finds rim-enhancement.
