摘要 目的探讨甲状腺微小乳头状癌(PTMC)应用高分辨率超声检查对甲状腺外侵犯情况的诊断作用。方法选择PTMC患者100例,共有结节120个,均为我院2015年1月至2017年12月收治,采用高分辨超声予以诊断,依据结节接触邻近甲状腺被膜的程度,对有无甲状腺侵犯予以判断。结果经超声检查,与被膜接触密切的结节62个,经手术病检证实,其中40个存在甲状腺外侵犯;与被膜无接触的结节58个,经手术病检证实,其中9个存在甲状腺外侵犯,于甲状腺内局限的结节49个。提示PTMC与邻近被膜接触密切时,明显增加了外侵犯概率。PTMC与被膜接触面积≥20%的患者,有最高特异度、阳性预测值、阴性预测值,与其他接触级别比较,差异具统计学意义(P<0.05)。结论针对临床收治的PTMC患者,采用高分辨超声进行检查,通过评估结节与邻近被膜接触情况,可为对甲状腺有无外侵犯诊断提供判断依据,其中,接触面积≥20%时,有更高判断价值。
