乳腺良恶性病变CT表现

目的　明确乳腺良恶性病变影像学表现。方法　对 47例有X线钼靶和CT资料并为病理证实的乳腺疾病患者资料进行分析 ,恶性组 2 0例 ,平均年龄 50 .0岁 ;良性组 2 7例 ,平均年龄 40 .6岁。CT扫描使用东芝Xprees/GX螺旋CT机 ,扫描范围从腋窝至乳房下界。其中 2 6例行增强扫描 ,均俯卧位螺旋扫描 ,上胸、腹部垫高 ,使乳房自然下垂 ,双前臂交叉放在头上。结果　恶性组毛刺肿物 14例 ,分叶肿物 10例 ,钙化肿物 5例 ,透亮环肿物 4例 ,囊壁肿物 1例 ,胸肌粘连 9例 ,皮肤增厚 8例 ,乳头内陷 4例 ,大导管牵拉征 7例 ,Cooper韧带增粗 5例 ,淋巴结肿大 8例 ;强化后CT值升高 >40HU。良性组 :圆形及卵圆形肿物 10例 ,分叶肿物6例 ,斑片及条索样肿物 5例 ,透明晕肿物 4例 ,囊壁肿物 2例 ,钙化肿物 1例 ,毛刺肿物 1例 ,导管牵拉征 4例 ,皮肤增厚 4例 ,Coop er韧带增粗 2例 ,脂肪间隙变形 1例 ,乳头内陷 4例。结论　CT是诊断乳腺疾病的良好方法

CT Findings:Benign and Malignancy Disorder in the Breast

Objective To study the findings of mammography and CT in disease of the breast.Methods Fourty-seven cases were reported,all cases were confirmed by pathology:including the breast malignancy neoplasm(age mean 51 years,20 cases)and the benign disease(age mean 40.6 years,27 cases).All cases underwent plain scanning and 26 cases underwent contrast-enhanced scanning with use of a helical CT(TOSHIBA Xpress/GX,Japanese).For each patient,a field view was chosen that would depict the whole breast,as well as the ipsilateral axillary and internal mammary chains.Patients were imaged in the prone position with the hands adove the head.All cases were referred for mammography using routine craniocaudal and mediolateral oblique views.Results The signs of mammography and CT in disease of the breast were as followed:spiculated lesion,lobulated mass,calcificated mass,bright-ring mass,duct retraction,involved Coopers ligament,involvement of local skin,chest-wall invasion,deformed adipose space.Axillary lymph node metastasis.Breast CT was positive in 10 of 10 malignancy neoplasm with an enhancement of 40 HU or more.Conclusion CT is a good method in examinating disease of breast.
