摘要
目的 探讨超声对局灶性桥本甲状腺炎(FHT)的诊断价值.方法 回顾性分析经手术和病理证实的15例FHT患者的二维声像图特征及彩色多普勒血流(CDFI)情况.结果 15例FHT患者的二维超声均表现为甲状腺内单发病灶,灶外腺体回声尚均匀.其中11个(73.3％)病灶边界清晰,12个(80％)形态规则,12个(80％)呈低回声,8个(53.3％)回声不均,似“地图样”,无明显占位效应,2个(13.3％)内见斑状强回声钙化；CDFI表现:4个(26.7％)血流信号极为丰富,呈局灶性“火海征”,10个(66.7％)血流信号稍丰富,1个(6.7％)无明显血流信号.结论 FHT具有特征性的声像图特点,超声检查具有一定的临床诊断价值.
Abstract
Objective To explore the ultrasound diagnostic value in focal hashimoto thyroiditis (FHT). Methods Gray-scale and color Doppler flow images (CDFI) of 15 FHT patients confirmed by surgery pathology were retrospectively analyzed. Results Fifteen single lesions in the thyroids of 15 FTH patients were detected by gray-scale ultrasound scan. The around parenchyma was well-distributed. Ele-ven(73. 3% ) of 15 lesions were of well-defined margin. Twelve(80% ) of 15 lesions were regular and 12 (80% ) lesions were hypoechoic. Eight lesions with uneven echogenicity were like the "map" and were of no significant occupation effect. Hyperechoic calcification was detected in 2(13. 3% ) lesions. Extremely abundant blood flow sign as "focal inferno" was showed in CDFIs of 4(26.7% ) lesions. Ten(66. 7% ) of 15 lesions showed mildly abundant blood flow sign and 1 (6. 7% ) lesion had no blood flow sign. Conclusion The FHT has characterized ultrasound appearance and ultrasound is helpful to the clinical diagnosis of FHT.
