目的探讨超声诊断甲状腺恶性结节的病理特征及其超声二维、彩色多普勒血流显像检查中误诊的原因。方法对16例术后病理确诊而超声误诊的甲状腺癌病例进行回顾性分析。结果16例患者中，超声诊断为甲状腺腺瘤12例，结节性甲状腺肿4例；术后病理确诊甲状腺乳头状癌13例，甲状腺滤泡癌2例，甲状腺髓样癌1例。结论甲状腺结节良恶性的鉴别是超声关注的焦点，甲状腺恶性结节的病理表现多样性和复杂性及超声表现不典型、良恶性结节的共存导致超声鉴别诊断的困难。

Objective To investigate pathological characteristics in diagnosing malignant thyroid nodules with ultrasonography ,and reasons for misdiagnosis in ap-plication of 2 -dimensional ultrasonography and colour doppler flow imaging .Methods Retrospective evaluation of 16 postoperative malignant thyroid nodules cases which had been misdiagnosed by ultrasonography preoperation.Results Among the 16 cases,12 were diagnosed with thyroid adenoma,4 were nodular goiter.Final postop-erative diagnosis were:13 thyroid papillary adenoid cancer,2 thyroid follicular adenoid cancer,1 thyroid medullary cancer.Conclusions The differential diagnosis of be-nigh and malignant thyroid nodules is the focus of ultrasonography .The variable and complex pathological characteristics of malignant thyroid nodules ,inconsistent repre-sentations on ultrasonography and coexist of benigh and malignant thyroid nodules are the main reasons for misdiagnosis .
