【摘要】：目的:探讨乳腺浸润性筛状癌(ICC)的超声声像图特征与其病理分型的相关性,旨在提高超声诊断该病的准确率。方法:回顾性分析2010年1月—2015年12月在我院普外科接受手术治疗并经病理证实的9例乳腺ICC患者的超声声像图表现,并比较不同病理类型之间的差异。结果:9例患者均为女性,平均年龄59.6岁(38~76岁)。所有9例患者均于术前接受超声检查。肿块直径大小范围9.8~42mm。声像图显示肿块形态欠规则3例(33.3%),形态不规则6例(66.7%);边界清晰2例(22.2%),边界欠清或不清7例(77.8%);内部回声均匀3例(33.3%),不均匀6例(66.7%);所有9例病灶均呈低回声,2例患者(22.2%)肿块内见细钙化。彩色多普勒血流显像示3例(33.3%)肿块内部未测及无明显血流信号,5例(55.6%)测及点状血流信号,1例(11.1%)测及条状血流信号。术前超声BI-RADS分类:4A类3例,4B类4例,4C类2例,恶性诊断敏感度为66.7%(6/9)。依据病理学特征将ICC分为单纯型(3例),含有小管癌型(2例)及混合型(4例)。3例单纯型均为4A类,2例含有小管癌型均为4B类,4例混合型中2例为4B类,2例为4C类。结论:不同病理类型的乳腺ICC的声像图表现各具相应的特点,其不同的表现反映了肿瘤组织病理学的变化。单纯型ICC的声像图偏向良性表现,是造成该型恶性诊断敏感度较低的主要原因。
[Abstract]:Objective: to investigate the correlation between the ultrasonographic features of invasive ethmoid carcinoma of the breast (ICCC) and its pathological classification. Methods: the ultrasonographic findings of 9 patients with breast ICC, who underwent surgical treatment in our hospital from January 2010 to December 2015, were analyzed retrospectively in order to improve the accuracy of ultrasound diagnosis. The differences between different pathological types were compared. Results all 9 patients were female. The mean age was 59.6 years old and 38 / 76 years old. All the 9 patients were examined by ultrasound before operation. The diameter of the mass ranged from 9.8 mm to 42 mm. Sonogram showed that the shape of the mass was not regular in 3 cases and irregular in 6 cases. The boundary was clear in 2 cases and the boundary was unclear or unclear. 77.8% of the tumors were not clear; 3 cases had homogeneous internal echo, 66.7% had heterogeneity; all the 9 lesions were hypoechoic in 2 cases and 22. 2) calcification was found in the masses. Color Doppler flow imaging showed 3 cases with 33. 3%) and had no apparent blood flow information. 5 cases (55.6%) and 1 case (11. 1) to measure the blood flow signal. BI-RADS was used to classify 3 cases of 4B class and 4 cases of 4C group. Before operation, there were 2 cases of 4C type, 3 cases of category 4A and 4 cases of category 4B, respectively. The sensitivity of malignant diagnosis was 66.7 / 9. According to pathological features, ICC was divided into simple type (n = 3) and mixed type (n = 4) and mixed type (n = 4). Conclusion: the sonographic features of different pathological types of breast ICC are different. Its different manifestations reflect the histopathological changes of the tumor, and the ultrasonic images of simple ICC tend to be benign, which is the main reason for the low sensitivity in the diagnosis of this type of malignancy.
