结节性甲状腺肿的声像图表现及鉴别诊断

Sonographic appearance and Differential Diagnosis of Nodular thyroid Goiter

分析结节性甲状腺肿（结甲）的声像图特征，探讨结甲与甲状腺腺瘤。甲状腺癌的鉴别诊断。方法；结甲２３７例，腺瘤３９例，甲状腺癌５７例，术前７．５ＭＨｚ高频探头观察结节数目和内部回声结构。结果：１７１例结甲（７２％）表现为多结节不对称分布在一侧或双侧肿大的甲状腺内，６６例（２８％）单结节，内部情况分为囊性、实性、混合性回声结构，并分析了１４例误诊为腺瘤的原因和甲状腺癌的声像图特征。结论：结甲声像图多样，仔细扫查双侧甲状腺，对比观察结节内、外回声，可为诊断提供依据。

To study the sonographic characteristics of nodular thyroid goiter (NG) and explore the value of ultra sonography (US) in differentiating NG from thyroid adenoma or carcinoma. Methods: 237 patients with NG, 39 adenoma and 57 carcinoma were examined by 7. 5MHz transducer before operation. The number and echo structure of nodes were obserued. Results: 171 cases of NG (72% ) presented scattering nodes in one or both sides of enlarged gland.66 cases of NG (28% ) presented single node with substantial, cystoid or mixed internal echo structure. Conclusions: Analysis of the internal and external echo structure of NG nodes is helpful in diagnosing thyroid disease.
