甲状腺微小癌的超声诊断价值

目的 探讨甲状腺微小癌的超声特征及其诊断价值.方法 回顾性分析40例患者56个结节的超声特点.结果 本组56个癌结节病理均为乳头状癌.表现为边界模糊者53个结节;内部有微钙化者49个结节;结节内部表现为低回声（等于或低于颈前肌回声）32个结节;结节内血流信号丰富者仅26个结节;伴颈部淋巴结转移者43个结节.诊断明确46个结节,误诊20个结节,超声检出率为82.1%,误诊率为17.9%.结论 甲状腺微小癌的超声特征对其诊断有较高的价值.

Diagnostic value of ultrasound on thyroid microcarcinoma

Objective To discuss ultrasonic characteristicof thyroid microcarcinoma and the diagnosis value. Methods To retrospectively analyze the ultrasonic charaeteristieof 56 thyroid nodulesfrom 40 patients. Results All the fifty-six cancer nodules were papillary carcinoma approved by pathology, and 53 of them performed fuzzy boundary ,49 nodules present internal mierocalcifications, 32 nodules present low internal echo ,26 nodules with abundant blood flow signal ,43 nodules with neck lymph node metastasis. Forty-six cases were clearly diagnosed. Twenty cases were misdiagnosed. Therate of ultrasound detection was 82.1% and themisdiagnosis rate was 17.9%. Conclusions Ul-trasound had important practical value on diagnosis of thyroid micro carcinoma.
