摘　　要：目的探讨单发局灶性甲状腺炎症(SFT)的超声表现。方法回顾性分析37例SFT常规超声及弹性成像表现。结果病灶均为低回声,边界清晰。33例(89.2%)边缘模糊,4例(10.8%)边缘锐利。28例(75.7%)形态规则,9例(24.3%)形态不规则。35例(94.6%)上下/前后径比值>1,2例(5.4%)≤1。1例(2.7%)内部见微小强回声。彩色多普勒血流分布显示5例(13.5%)无血流,28例(75.7%)周边血流,3例(8.1%)中央血流,1例(2.7%)混合血流。弹性成像显示18例(48.7%)I型,16例(43.2%)Ⅱ型,3例(8.1%)Ⅳ型。结论 SFT未表现甲状腺炎症典型特点,而具有与乳头状癌(PTC)类似的超声征象,弹性成像显示病灶相对质地较软。Objective To investigate the ultrasonographic findings of solitary focal thyroiditis （SFT）. Methods Retrospectively analyzed the conventional ultrasonographic （US）findings and the elasticity scores of real time elastography in 37 cases of SFT. Results All lesions were hypoechogenicity and well defined in border in US. The margin was smooth in 89.2% and sharp in 10. 8% of lesions. Twenty-eight cases were regular in shape, and nine cases were irregular. Two cases were taller than wide （anteroposterior diameter was longer than longitudinal dimension）. The foci echogenicity was seen in one lesion. On Doppler analysis, 13.5 % of lesions were avascularity, 75.7 % were periphery vascularity, 8.1% were internodular vascularity and 2.7% were internodular and periphery vascularity. On real timeelastography, 48.7 % of SFT were pattern Ⅰ, 43.2 % were pattern Ⅱ, and 8.1% were pattern Ⅳ. Conclusions SFT has a few of sonographic findings mimicking PTC in US, with a relative lower elasticity scores in elastography.
