结节性甲状腺肿超声声像与手术病理对照分析

Comparative analysis of the ultrasonographic and operative and pathological result of rodular goiter

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 ultrasonographic characteristics of rodular goiter and the clinical diagnostic value.Methods The ullra.sonographic characteristics of rodular goiter in 46 patients treated in our hospital were analyzed retrospectively,which were compared with operative and pathological results.Results There were many characteristics in ultrasonography of rodular goiter.Firstly,it was usually found bilaterally.Secondly,there were many nodulated inhomogeneous echoes,possibly without smooth envelope and clear boundary.Thirdly,there were hemorrhage,cysloid and calcification in some nodes.Fourthly,imaging of CDFI found abundant blood flow around some nodes.The coincident ratio of ultrasonography in the nodes larger than 1 cm was 78.5%.To the others,located diagnosis was accurate,and quality diagnosis was difficult.Conclusion Ultrasonography is valuable to the diagnosis of rodular goiter.
