摘　　要：目的:探讨常规超声对乳腺黏液癌的诊断价值。方法:收集医院收治且经病理证实的35例乳腺黏液癌患者超声检查资料,对乳腺黏液癌的病灶大小、边界、内部回声、有无小暗区及微钙化、后方回声是否增强、病灶纵横比、血流信息及腋窝有无淋巴结转移进行分析,应用超声乳腺影像报告和数据系统(BI-RADS)分类标准分为3类结节17例及4类结节18例。结果:在35例乳腺黏液癌患者的超声图像表现中:病灶边界清晰占60%(21/35),形态较规则占74%(26/35),内部以低回声为主占97%(34/35),可伴无回声区占86%(30/35),病灶后方回声增强占89%(31/35),纵横比<1占100%(35/35),少数结节内见微钙化占5.7%(2/35);其中病灶内部血流0级10例,1级20例,2级5例。35例患者中腋窝淋巴结转移3例占8.9%(3/35)。结论:乳腺黏液癌患者的超声影像中,大多数表现为边界清楚、形态较规则、内部有无回声区及后方回声增强等,以上这些影像特征是乳腺良性结节具备的超声影像特征,因此很容易误诊为良性结节,尤其是结节内伴无回声区对单纯型黏液癌有重要的提示意义。Objective:To explore the diagnostic value of routine ultrasonography in mucinous carcinoma of mammary gland.Methods:The data of ultrasonic testing of 35 patients with mucinous carcinoma of mammary gland who admitted to hospital and were confirmed by pathology were selected.And the size,boundary,internal echo,presence or absence of small dark areas and micro-calcification,whether or not enhancement of behind echo,the aspect ratio,blood flow information and lymph node metastasis of axilla about mucinous carcinoma of mammary gland were analyzed.And they were divided into 17 cases with 3 type of nodule and 18 cases with 4 type of nodule by applying the standard of the classification of image report of ultrasound and data system(BI-RADS).Results:The performances of ultrasound images of 35 patients with mucinous cancer of mammary gland showed the ratios of the lesion with clear border,the lesion with relatively regular shape,the lesion interior that mainly was low-echo,the lesion that might accompany with no echo area,the lesion which echo was enhanced at rear,the lesion which aspect ratio was less than 1,the lesion that there was micro-calcification within a few nodule were 60%(21/35),74%(26/35),97%(34/35),86%(30/35),89%(31/35),100%(35/35)and 5.7%(2/35),respectively.In these patients,the blood flow of lesion interior was 0 grade in 10 cases,and that was 1 grade in 20 cases,and that was 2 grade in 5 cases.In addition,3 cases[8.9%(3/35)]occurred axillary lymph node metastasis in 35 patients.Conclusion:In ultrasonic image of patients with mucinous cancer of mammary gland,most of them showed clear boundary,relatively regular shape,with or without echo within the interior,and echo with enhancement at rear.These above image features are ultrasonic image features that benign nodule of mammary gland possesses,therefore,they are apt to be misdiagnosed as benign nodule.Especially,the nodule that accompanies with no echo area has important hint significance for simple type of mucinous carcinoma.
