目的：探讨超声误诊结节性甲状腺肿的原因。方法在被超声误诊的54例结节性甲状腺肿中，从甲状腺结节的声晕、包绕血流、囊性变、内部血流、纵横比、钙化灶及RI等各方面进行分析。结果54例结节性甲状腺肿被超声误诊为甲状腺腺瘤30例，甲状腺腺瘤囊性变5例，高功能腺瘤3例，甲状腺癌16例。误诊的主要原因是过高地看待了某些超声征象的特异性，片面地强调了这些超声征象所致。结论如果对甲状腺结节的各种超声征象进行综合考虑，则可减少对结节性甲状腺肿的误诊率。

Objective To explore the factors leading to misdiagnosis of nodular goiter by ultrasonography. Methods In the 54 cases of misdiagnosised nodular goiter by ultrasonography,the acoustic halo,surrounding blood flow,cystic changes,internal blood flow,aspect ratio,calcification and RI of thyroid nodules were analysed. Results 54 cases of nodular goiter were misdiagnosed as thyroid adenoma in 30 cases,thyroid adenoma cystic change in 5 cases,high functional adenoma in 3 cases and thyroid carcinoma in 16 cases.The main misdiagnosised reason were that the specificity of some ultrasonographic signs were overestimated, and these ultrasonographic signs were one-sided emphasized. Conclusion If ultrasonographic signs of thyroid nodules were synthetical y considered,the misdiagnosis rate of nodular goiter could be decreased.
