结节性甲状腺肿的超声征象与病理对比分析

Analysis of the relationship between the sonographic features and the pathology of nontoxic nodular goiter

目的探讨结节性甲状腺肿的声像图表现与病理的关系。方法分析58例结节性甲状腺肿患者100个结节的二维及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45个,混合性回声结节41个。15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1个,出血囊性变13个,囊性变乳头状增生3个;结节性甲状腺肿伴钙化23个。结论二维超声结合彩色多普勒超声能反映出结节性甲状腺肿的基本病理特征,可与腺瘤和甲状腺癌相鉴别。

Objective To investigate the relationship between the sonographic features and the pathology of nontoxic nodular goiter. Methods In 58 patients with nodular goiter, 100 nodules were evaluated by high-resolution sonography and color Doppler sonography. Results Among the 100 nodules, 14 had isoechoic or hypoechoic texture, 45 had anechoic texture, 41 had mixed echoic texture. 15 nodules showed increasing intranodular blood flow, and 3 nodules with“halo”showed perinodular blood flow. Pathologically, 91 nodules had cystic degeneration, 13 nodules had cystic degeneration with haemorrhage, and 3 nodules had cystic degeneration with mastoid hyperplasia. 23 nodules had degeneration with calcification. Conclusion High-resolution sonography and color Doppler sonography could show the pathologic characteristics of nontoxic nodular goiter, which are helpful in differential diagnosis with adenoma and thyroid carcinoma.
