甲状腺癌的超声误诊分析

Ultrasound Diagnosed Erroneously Carcinoma of the Thyroid Gland

目的 分析甲状腺癌超声声像图特征 ,降低超声误诊或漏诊率。方法 总结术后病理确诊 ,超声误诊的2 2例甲状腺癌声像图特征。结果 2 2例甲状腺癌中钙化 1 3例 ,其中微钙化 9例。肿块直径小于 1 .5cm 7例。甲状腺两种疾病共存 9例。结论 微钙化是乳头状癌的一个特征性表现。肿块直径小于 1 .

Objective To analyze the ultrasonographic characteristics of the thyroid gland in order to lower the ratio of misdiagnosis and omission of ultrasonography.Methods 22 cases of thyroid carcinomas diagnosed by ultrasound were retrospectively analyzed and compared with the results of post-operative pathological diagnosis.Results There were 13 calcified lesions in the 22 cases,in which there were 9 cases of micro-calcified lesions.Seven cases with mass's diameter less than 1.5 cm were found.Nine cases were complicated with two diseases in the thyroid glands simultaneously.Conclusions Micro-calcified lesion was a specific feature for papillary carcinomas of the thyroid gland.It is difficult for a correct ultrasound diagnosis if the mass's diameter was less than 1.5 cm or there were more than two kinds of diseases in the thyroid gland.
