结节样桥本甲状腺炎的超声表现

目的探讨结节样桥本甲状腺炎(NHT)的超声表现。方法回顾性分析20例NHT的超声表现,以同期40例桥本甲状腺炎(HT)基础上乳头状甲状腺癌(PTC)作为对照,比较二者在甲状腺腺体大小、病变数目、回声、声晕、血流信号、钙化、声晕及颈部淋巴结肿大等超声特点的差异。结果 NHT多表现为有声晕的中高回声,可见钙化、极低回声表现及囊性变。与HT基础上PTC比较,在腺体大小、病变数目、回声、声晕及钙化表现方面差异有统计学意义(P均<0.05)。结论 NHT与HT基础上PTC的超声表现存在差异;超声有助于鉴别NHT。

Ultrasonic appearances of nodular Hashimoto thyroiditis

Objective To explore ultrasonic features of nodular Hashimoto thyroiditis (NHT). Methods Ultrasonic features of NHT in 20 pathologically confirmed patients were retrospectively analyzed, while 40 papillary thyroid carcinoma (PTC) patients with Hashimoto thyroiditis (HT) background disease were settled as controls. Ultrasonic features such as size of the gland, lesion number, echotexture, halo, vascularity, calcification, neck lymphadenopathy were compared between them. Results NHT often appeared as iso- or hyper-echoic nodules with hypoechoic halo, goiter was commonly seen, calcification, extremly hypoechoic menifestations and cystic change could be observed. Compared with PTC with HT background disease, the incidence of goiter, lesion number, echotexture, halo and calcification had statistically significance (all P<0.05). Conclusion The differences between NHT patients and PTC patients with HT background disease maybe helpful to the differential diagnosis.
