特殊甲状腺癌的超声检查分析

Sonographic evaluation of the special thyroid carcinoma

目的分析超声扫描时有特殊表现的甲状腺癌病例，进一步提高超声诊断甲状腺癌的准确率。方法收集2001年1月至2007年12月有特殊超声表现的病例，共9例。根据超声特征分为两种类型：（1）弥漫性甲状腺恶性病变8例，（2）明显突出于腺体外的囊性病变1例。记录其二维超声及彩色多普勒超声表现。结果第1类病变，其二维超声表现具有明显特征性，彩超无明显特异性，8例均诊断正确；第2类病变，超声无特异表现，诊断错误。结论第1类病变具有明显特征，诊断正确率高，可作为首选检查方法。第2类病变，超声未发现特征性，尚需进一步研究。

Objective To analyze the cases of thyroid carcinoma with special sonographic features, so as to increase the accuracy of sonographic diagnosis for thyroid carcinoma. Methods The sonographic characteristics of 9 patients with special sonographic appearance were analyzed. According to the sonographic features, they were divided into two kinds： 8 cases suffered from thyroid diffuse malignant lesions, and one case showed cystic lesion sticking out of the thyroid. The sonographic appearance of gray scale and color Doppler characteristics of the lesions were recorded. Result In the first kind of lesions, the dimensional ultrasound appearance of gray scale had an apparent feature, however, its color Doppler characteristics had no apparent feature, and all of the 8 cases were diagnosed correctly by ultrasound. In the second kind of lesion, the sonographic appearance of gray scale and color Doppler had no special features, so the case was diagnosed as benign disease wrongly by ultrasound. Conclusion The first kind of lesions has apparent sonographic features, sonographic diagnosis can serve as the first choice. However, the second kind of lesion had no apparent sonographic feature.
