目的分析结节性甲状腺肿的高频超声表现,提高超声诊断结节性甲状腺肿的水平。方法回顾分析63例经手术病理证实的结节性甲状腺肿高频超声表现。结果结节性甲状腺肿超声表现主要为甲状腺双侧叶非对称肿大,结节多为多发,结节内部回声不均匀,部分伴有囊性变,结节内可见钙化,结节边界清,无包膜或包膜不完整,无晕环,结节之间无正常甲状腺组织,结节周边及内部血流信号不丰富。结论结节性甲状腺肿的高频超声表现多样,具有一定特征性,超声是诊断结节性甲状腺肿的一种重要方法。
Objective To analyze the high frequency ultrasound findings of nodular goiter and improve the level of diagnosis of nodular goiter by ultrasound. Methods Retrospective analysis of 63 cases of pathologically confirmed nodular goiter high frequency ultrasound. Results The sonographic features of nodular goiter were mainly asymmetric enlargement of bilateral bilateral thyroid lobes, multiple nodules, uneven echogenicity of nodules, cystic degeneration in part, calcification in nodules, clear nodule border, No capsule or capsule is not complete, no Halo, no normal nodules between the thyroid tissue, peripheral and internal nodular blood flow signal is not rich. Conclusion High-frequency ultrasound of nodular goiter has various characteristics and has certain characteristic. Ultrasound is an important method to diagnose nodular goiter.
