超声对甲状腺癌漏误诊原因的探讨

目的：分析超声检查中甲状腺癌漏误诊的原因。方法选择2010年1月~2013年1月在我院住院治疗的甲状腺癌患者36例为研究对象。分析这些病例术前超声与术后病理结果，对比正常超声表现与误诊超声表现。结果术后病理证实36例患者中有7例为恶性肿瘤，其余均为良性肿瘤，误诊6例，漏诊1例。结论甲状腺癌超声表现中与良性占位描述类似的病灶，病灶形态规则、边界清晰、包膜完整，病灶内无强回声，尤其是良性结节与恶性病变同时出现时，易被误诊、漏诊。

To investigate the reasons of missed diagnosis and misdiagnosis of thyroid carcan by Ultrasonography

Objective To analyze the reasons of missed diagnosis and misdiagnosis of thyroid carcinoma by Ultrasound. Methods A total of 36 cases with thyroid cancer who were treatment in our hospital from January 2010 to January 2013 were selected as the objects of study. These cases of preoperative ultrasonography and postoperative pathologic results were analyzed. Normal ultrasound findings and misdiagnosis of ultrasonography were compared. Results Postoperative pathology confirmed 36 cases of patients with malignant tumors in 7 patients,the others were benign tumors,6 cases of misdiagnosis,missed diagnosis in 1 cases. Conclusion Lesions of thyroid carcinoma by ultrasound with benign space occupying similar are easily misdiagnosed and missed diagnosis. Lesion is morphology,it is sharpness of border and intact with clear membrane. Inner has no echo,especially the benign nodules and malignant lesions appear at the same time.
