29例乳头状甲状腺癌的超声诊断分析

Ultrasound Diagnosis on Papillary Thyroid Cancer:An Analysis of 29 Cases

目的分析乳头状甲状腺癌的超声表现特征,以提高甲状腺良恶性肿块的超声诊断及鉴别诊断水平。方法探讨我院29例病理证实为乳头状甲状腺癌肿块的术前超声检查,分析病灶的位置、回声、大小、内部有无钙化、后方回声、边界、内部的血流丰富程度、阻力指数及颈部淋巴结是否肿大。结果乳头状甲状腺癌声像图表现有以下特征:多呈实质低回声、后方回声多衰减、边界不清(无包膜)、纵横比>1、形态欠规则、呈浸润性生长、微钙化、高阻血流频谱、同侧颈部淋巴结转移等。结论掌握乳头状甲状腺癌超声表现特征,可提高对本病的认识,减少漏诊及误诊,为临床治疗提供有价值的信息。

Objective To investigate the sonography features of papillary thyroid carcinomas in order to improve its diagnosis and differential diagnosis. Methods Preoperative sonography of 29 patients with thyroid carcinoma confirmed by pathology were analyzed retrospectively. We analyzed the position, magnitude, calcification, the echo behind the tumor, boundary, the quantity, shape, speed, resistance index of blood vessel and whether with lymph tumescence on the neck or not. Results Papillary thyroid cancer had the following features audio and video charts： Mostly real low echo, rear multi-echo attenuation, border unclear （ no capsule ）, Aspect Ratio ~ 1, shape due to the rules, showing invasive growth, micro-calcification, blood flow impedance spectrum, the same side neck lymph node metastasis etc. Conclusion mastering the color Doppler flow imaging features of papillary thyroid carcinoma can improve the cognition of this disease, reduce missed diagnosis and misdiagnosis, improve the valuable diagnostic evidence to the clinical therapy.
