乳腺癌颈部淋巴结转移超声与CT诊断价值分析

目的观察乳腺癌颈淋巴结转移患者彩超声像图与CT影像表现及其相应诊断价值。方法回顾性分析经手术病理证实的80例乳腺癌患者临床资料,其中存在颈淋巴结转移者33例,无颈淋巴结转移47例。术前均行彩超、CT检查,观察乳腺癌颈淋巴结转移彩超与CT影像表现,分析彩超、CT对乳腺癌颈淋巴结转移的诊断价值。结果乳腺癌颈淋巴结转移彩超图像主要表现为边界不规则,可有微小钙化,出现乳头回缩、结构扭曲及局限致密,皮肤增厚或回缩。CT可见部分增大的淋巴结融合成团,转移淋巴结正常肾形结构丧失,呈类圆形或边缘浅分叶状。彩超与CT诊断乳腺癌颈淋巴结转移灵敏度、特异度、准确度、阳性预测值、阴性预测值差异无统计学意义(P>0.05)。结论彩超、CT诊断乳腺癌颈淋巴结转移均具有较高的诊断价值,具有一定的影像特点,临床可根据患者情况选择单独使用或者联合使用。

Diagnostic Value of Ultrasonography and CT in Cervical Lymph Node Metastasis of Breast Cancer

Objective To observe the findings and diagnostic value of color ultrasound image and CT in patients with breast cancer and cervical lymph node metastasis. Methods The clinical data of 80 patients with breast cancer confirmed by operation and pathology were analyzed retrospectively, including 33 cases with cervical lymph node metastasis and 47 cases without cervical lymph node metastasis. Color ultrasound and CT examinations were performed before operation. The imaging findings of cervical lymph node metastasis of breast cancer by color ultrasound and CT were observed. The diagnostic value of color ultrasound and CT on cervical lymph node metastasis of breast cancer was analyzed. Results The findings of color ultrasound images of cervical lymph node metastasis of breast cancer were mainly characterized by irregular borders, slight calcification, limited dense infiltration, structural distortion and nipple retraction, local skin thickening or retraction. CT showed that some enlarged lymph nodes merged into a mass, and all metastatic lymph nodes lost normal kidney-shaped structure and became rounded or shallowly lobulated. There were no significant differences in the sensitivity, specificity, accuracy, positive predictive value and negative predictive value between color ultrasound and CT in the diagnosis of cervical lymph node metastasis of breast cancer(P>0.05). Conclusion Both of Color ultrasound and CT have high diagnostic value and obvious image features in the diagnosis of cervical lymph node metastasis of breast cancer. They can be selected or combined according to the patient’s condition.
