目的探讨结节性甲状腺肿的声像图表现与病理改变的关系,提高超声诊断价值。方法分析62例结节性甲状腺肿106个结节的高频和彩色多普勒声像图表现。结果等回声或低回声结节14个,无回声结节47个,混合性回声结节45个。16个结节内可见稍增多的点线状血流信号,3个有声晕的结节在结节周边可见到血管信号。术后病理诊断为结节性甲状腺肿伴囊性变92个,其中出血囊性变12个,囊性变乳头状增生2个;结节性甲状腺肿伴钙化25个。结论高频及彩色多普勒超声能反映出结节性甲状腺肿的病理特征,并与甲状腺腺瘤和甲状腺癌相鉴别。
Objective To investigate the relationship between sonographic findings and pathological changes of nodular goiter to improve the diagnostic value of ultrasound. Methods High-frequency and color Doppler sonographic findings of 106 nodules of nodular goiter were analyzed. Results such as echo or low echo nodules 14, no echo nodules 47, mixed echo nodules 45. 16 nodules showed a slight increase in the point of linear blood flow signals, nodules with three halo halo visible in the periphery of the nodules. Postoperative pathological diagnosis of nodular goiter with cystic degeneration 92, including hemorrhagic cystic degeneration 12 cystic papillary hyperplasia 2; nodular goiter with calcification 25. Conclusion High-frequency and color Doppler ultrasound can reflect the pathological features of nodular goiter and differentiate it from thyroid adenoma and thyroid cancer.
