【摘要】 目的总结男性乳腺癌超声和X线表现特征。方法经手术病理证实的男性乳腺癌患者46例,依据乳腺影像报告和数据系统(BI-RADS)标准对其超声、X线影像表现进行分析。结果 42例超声表现特征:病变位于乳晕中央区13例、偏心性29例,病变类型为肿块39例(形态规则14例、不规则25例,边缘清晰13例、不清晰26例)、低回声区3例,病变内部回声不均匀39例、囊实性回声3例,病变后方回声衰减13例、增强15例、无变化14例,病变周围回声增强33例、无变化9例,病变血流丰富28例、边缘血流4例、血流不丰富10例,伴有患侧腺体发育20例、无患侧腺体发育22例。44例X线表现特征:病变位于乳晕中央区15例、偏心性29例,病变类型为肿块25例、肿块伴钙化13例、局限致密3例、局限致密伴钙化3例,伴有患侧腺体发育21例、无患侧腺体发育23例;38例肿块型病变中,属于高密度36例、等密度2例,形态规则13例、不规则25例,边缘清晰7例、不清晰31例。结论男性乳腺癌超声和X线表现为非乳晕中央区呈偏心生长的不规则肿块最常见,通常不具有女性乳腺癌边缘毛刺的典型恶性征象表现,但可伴有乳腺发育;超声上当病变表现为囊实性回声肿块时,则更倾向于乳腺癌;X线上如出现钙化对乳腺癌诊断特异性更高。更多还原

【Abstract】 Objective To summarize the breast ultrasonographic and mammographic features of male breast cancer.Methods A retrospective analysis of 46 male patients with breast cancer confirmed by pathology was conducted.Ultrasonography and mammography images were analyzed based on BI-RADS criteria.Results In 42 cases of ultrasonography,13 cases of lesions were in the central areola,and 29 cases were eccentric to the nipple.There were 39 case of mass type(shape was irregular in 25 and round in 14,margin was unclear in 26 and clear in 13),and another 3 had hypoechoic areas.Internal echo was uneven in 39 cases,mixed cystic and solid in 3.Posterior acoustic was enhancement in 15 cases,shadowing in 13 and no change in 14.Echo halo was strong in 33 cases and no change in 9.Twenty-eight cases had rich blood flow signal,4 had vessels in rim and 10 had absent vascularity.There were 20 cases with breast gynecomastia and22 without.In 44 cases of mammography,15 cases of lesions were in the central areola,and 29 cases were eccentric to the nipple.The finding of carcinoma was masses in 25,masses with calcifications in 13,focal asymmetry in 3 and focal asymmetry with calcifications in 3.There were 21 cases with breast gynecomastia and 23 without.Of 38 cases of masses or masses with calcifications on mammography,density was high in 36 and equal in 2,shape was irregular in 25 and round in 13,margin was unclear in 31 and clear in 7.Conclusions The irregular masses in the non-areolar central area and in the eccentric growth are the most common manifestations of male breast cancer on both ultrasonography and mammography,but they do not have the malignant characteristics of female breast cancer,such as spiculated margin.Male breast cancer can also be accompanied with breast gynecomastia.On ultrasonography,it is more inclined to male breast cancer when the lesion is a mixed cystic and solid mass.The calcification on mammography is more specific for the diagnosis of male breast cancer.更多还原
