桥本氏甲状腺炎合并乳头状癌的声像图特点分析

ULTRASOUND CHARACTERISTIES OF PAPILLARY THYROID CARCINOMA WITH HASHIMOTO,S THYROIDITIS

目的:总结桥本氏甲状腺炎(Hashimoto’s thyroiditis,HT)合并乳头状癌(Papillary thyroid carcinoma,PTC)声像图特征。方法:回顾分析130例HT合并结节的声像图特点及甲状腺相关抗体资料,并与术后病理结果对比,做相应统计学分析。结果:HT合并PTC结节符合一般恶性结节特点,但部分伴有粗大钙化。纵横比大于1及缺乏低回声晕环较血流更具有诊断价值。周边淋巴结肿大无助于PTC的诊断,除非其内可见微钙化。HT合并PTC术前超声诊断率明显低于良性结节诊断组。结论:HT合并PTC有一定特征性声像图改变,目前超声诊断率仍较低,需提高认识,减少误诊。

Objective： To summarize ultrasonographic characteristics of Papillary thyroid carcinoma（ PTC） with Hashimoto＇s thyroiditis（ HT）. Methods： In this retrospective study,130 patient records were examined for ultrasonographic features and thyroid autoantibodies. C ompared with the pathological results,and the appropriate statistical analysis was carried out. Results： PTC with HT complied with generally malignant nodules characteristics,some associated with coarse calcifications; aspect ratio of nodule greater than 1 and the lack of a hypo-echoic halo had more diagnostic value than the blood flow.Peripheral lymph nodes did not contribute to the diagnosis of PTC,unless the micro-calcification was visible within them. PTC with HT ultrasound diagnosis rate was significantly lower than that in the preoperative diagnosis of benign nodules group. Conclusions： Inspite of characteristical appearance,ultrasound diagnosis rate for PTC with HT is low,it is necessary to raise doctors,s awareness for PTC with HT.
