摘　　要：目的探讨超声诊断甲状腺微小乳头状癌的常见误诊原因。方法回顾性分析经病理证实的82例甲状腺微小乳头状癌超声征象，分析其误诊原因。结果82例甲状腺微小乳头状癌，误诊27例。病灶最大径0．5～1cm组与≤0．5cm组误诊原因在边界、晕环及结节数目之间差异有统计学意义（P〈0．05）。其中最大径在0．5～1cm的病灶边界、微钙化、声晕在其正确提示组与误诊组间差异有统计学意义（P〈O．05）。最大径≤0．5cm的病灶，其中纵横比、结节数目在其正确提示组与误诊组间差异有统计学意义（P〈0．05）。结论PTMC误诊原因在不同病灶大小之间有所不同，病灶最大径在0．5～1Gift时表现为边界清晰、有声晕、无钙化等良性结节声像图特征时容易误诊，而最大径≤0．5cm时表现为纵横比〈1和多发结节时容易误诊。Objective To evaluate the reasons of mistaken diagnosis of papillary microcarcinoma of the thyroid （PTMC）. Methods We retrospected the reasons of mistaken diagnosis of 82 cases of PTMC which confirmed by pa thology and analyzed by one-way analysis of variance. Results All recorded 82 patients were diagnosed by pathology. 27 cases were misdiagnosed. There were significant difference of mistaken diagnosis between diameter 0.5-1 cm group and ≤0.5 cm group in boundary, halo sign and A/T. There were significant difference between misdiagnosed group and correct group in boundary, calicifications and halo sign to diameter 0.5-1 cm（P〈0.05） and in A/T and accompanying by multiple benign nodules to diameter ≤0.5 cm（P〈0.05）. Conclusions There were difference of mistaken diagnosis between diameter 0.5-1 cm group and ≤0.5 cm group. PTMC nodules with diameter 0.5-1 cm, which accompanied by features of benign nodules with well-defined and halo sign were easily misdiagnosed. Further more, PTMC nodules with diameter ≤0.5 cm that showed A/T〈1 and accompanied by multiple nodules were easily misdiagnosed or missed.
