超声诊断甲状腺微小乳头状癌的常见误诊原因分析

Analysis on the reasons of ultrasonic misdiagnosis on papillary thyroid microcarcinoma

目的:探讨超声诊断甲状腺微小乳头状癌常见误诊原因。方法:收治甲状腺微小乳头状癌患者75例,回顾其超声征象以分析误诊原因。结果:两组在声晕、微钙化、病灶边界上差距大(P<0.05)。结论:甲状腺微小乳头状癌误诊原因与病灶大小有关,最大径0.5~1.0 cm的误诊与无钙化、有声晕等良性结节的声像特征有关;而最大径≤0.5 cm与多发结节、纵横比<1的特征有关。

Objective:To investigate the causes of misdiagnosis of thyroid papillary microcarcinoma.Methods:75 patients with thyroid papillary carcinoma were selected,then their ultrasonic sign were analyzed retrospectively,in order to find out the causes of misdiagnosis.Results:The differences in acoustic halo, calcification and lesion boundary was significant between groups(P<0.05).Conclusion:Misdiagnosis of thyroid microcarcinoma were related to the size of lesions,sonographic features of benign nodules such as calcification and acoustic halo has relationship with misdiagnosis on thyroid papillary carcinoma that the maximum diameter of 0.5～1 cm,and the maximum diameter of less than 0.5 cm has relationship with multiple nodules,aspect ratio of less than 1.
