乳腺癌术后内乳淋巴结肿大的CT诊断

Value of CT in the diagnosis of metastasis of intramammary lymph nodes after operation with breast cancer

目的 :探讨 CT诊断乳腺癌术后内乳淋巴结转移检查方法及价值。方法 :挑选 CT检查发现内乳淋巴结肿大的 10例影像学资料进行分析。结果 :10例患者中 ,内乳淋巴结肿大 13枚。位于右侧内乳淋巴结链 5枚 ,左侧 8枚。 8例单侧单个肿大 ,1例双侧三处肿大 ,1例双侧两处肿大 ,距中线距离 2 .6cm～ 5.0 cm,距皮肤垂直深度 1.9cm～ 3 .0cm。淋巴结直径 0 .60 cm～ 1.0 0 cm。结论 :CT薄层增强扫描能准确显示转移之内乳淋巴结 ,为乳腺癌的 TNM分期及内乳淋巴结放射治疗照谢野的设定提供可靠影像学依据 。

Objective:To explore the method and value of CT in the diagnosis of metastasis of intramammary lymph nodes after operation with breast cancer.Methods:Analysis CT images of 10 patiens with metastasis of intramammary lymph nodes.Results:In 10 cases,13 metastasis of intramammary lymph nodes were found.5 nodes are in the right and 8 in the left.Singel lymph node metastasis in 8 cases,two in 1 case and three in 1 case.The distance from nodes to midal line is 2.6 cm～5.0 cm,average 3.4 cm.the depth from nodes to skin is 1.9 cm～3.0 cm,average 2.35 cm.diameter is 0.60 cm～1.00 cm,average 0.82 cm.Conclunsion:CT can display metasasis of intramammary lymph nodes accurately and give exact information for designing radiative field.
