目的:分析乳头状甲状腺癌颈部转移淋巴结的超声表现特征,以提高乳头状甲状腺癌颈部转移淋巴结的超声诊断准确率。方法:将经手术或细针穿刺病理检查证实为乳头状甲状腺癌并颈部淋巴结转移患者45例(128个淋巴结)作为研究对象,均经彩色超声检查,分析转移淋巴结的超声声像特点。结果:128个PTC颈部转移淋巴结主要分布在Ⅵ区(43.7%)、Ⅲ区(26.6%)、Ⅳ区(16.4%);长径8~38mm、短径4~25 mm。PTC颈部转移淋巴结彩色超声检查常表现为L/S<2、短径>8 mm、淋巴门结构消失、淋巴门结构偏移、边界清晰锐利、微钙化或微粗钙化并存、囊性变、周边型血管模式、混合型血管模式、动脉血流RI>0.7,其发生比率分别为87.5%、74.2%、68%、26.6%、72.7%、70.3%、43%、47.6%、35.2%、53.1%。结论:乳头状甲状腺癌颈部转移淋巴结超声显像具有一定特征性表现,认真综合分析各项声像图特征,能较好地提高颈部转移淋巴结的诊断正确率。
OBJECTIVE: To analyze the ultrasonographic features of cervical metastatic lymph nodes in papillary thyroid carcinoma and to improve the diagnostic accuracy of cervical lymph node metastases of papillary thyroid carcinoma. Methods: Forty-five patients (128 lymph nodes) with papillary thyroid carcinoma and cervical lymph node metastasis confirmed by operation or fine needle aspiration biopsy were examined by color sonography. The sonographic features of metastatic lymph nodes were analyzed. Results: The cervical lymph node metastases in 128 PTCs were mainly located in Ⅵ (43.7%), Ⅲ (26.6%), Ⅳ (16.4%), 8 ~ 38 mm in long diameter and 4 ~ 25 mm in short diameter. Color Doppler echocardiography showed that L / S <2, short diameter> 8 mm, lymphatic structure disappeared, lymphoid structure shift, the border was clear and sharp, micro-calcification or micro-calcification coexisted, cystic degeneration, Peripheral vascular pattern, mixed vascular pattern, arterial blood flow RI> 0.7, the incidence rates were 87.5%, 74.2%, 68%, 26.6%, 72.7%, 70.3%, 43%, 47.6%, 35.2%, 53.1 %. Conclusion: Ultrasonographic imaging of cervical lymph node metastasis of papillary thyroid carcinoma has certain characteristic manifestation. It can comprehensively analyze the features of sonography and improve the diagnostic accuracy of cervical lymph node metastasis.
