目的探讨结节性甲状腺肿的超声诊断及临床意义。方法对2003年1月至今上海市闸北区中心医院普外科诊治的46例结节性甲状腺肿行声像图特征与手术病理对照分析。结果结节性甲状腺肿的声像图特征:(1)双侧多发常见;(2)大小不等结节状回声,包膜可不光整,边界欠清晰,内部不均质回声;(3)部分病例有出血、囊变及钙化;(4)彩色多普勒(CDFI)部分结节周围血流丰富。直径≥1cm诊断符合率达78.5%,直径〈1cm定位准确,定性困难。结论 B超对结节性甲状腺肿诊断有很大价值。
Objective To investigate the ultrasonic diagnosis and clinical significance of nodular goiter. Methods From January 2003 to the present, 46 cases of nodular goiter diagnosed and surgically treated in general surgery department of Zhabei District Central Hospital of Shanghai City were analyzed retrospectively. Results Nodular goiter sonographic features: (1) multiple bilateral common; (2) ranging from nodular echo, the envelope may not be the whole, the border is not clear, the internal heterogeneous echo; (3) Some cases of bleeding, cystic change and calcification; (4) color Doppler (CDFI) part of the nodules around the blood flow rich. Diameter ≥ 1cm diagnosis coincidence rate of 78.5%, diameter <1cm accurate positioning, qualitative difficulties. Conclusion B ultrasound is of great value in the diagnosis of nodular goiter.
