摘　　要：目的:探讨甲状腺微小滤泡增生结节(FHN)的特征性CT征象。方法:收集经手术病理证实的69例(109个)甲状腺微小FHN(FHN组)和77例(90个)甲状腺微小乳头状癌(PTMC)(PTMC组)的临床和影像学资料。观察2组结节的CT征象,包括平扫密度、强化方式、囊变、边缘中断征、包膜征及钙化。对2组数据行组间比较,并分析相关CT征象的诊断效能。结果:2组CT平扫密度、强化方式、囊变、边缘中断征、包膜征及钙化差异均有统计学意义(均P<0.05)。阳性预测值高的征象包括CT平扫呈均匀等/高密度(1.000)、平扫密度不均匀(0.894)、强化不均匀(0.804)、囊变(0.838)。阴性预测值高的CT征象为包膜征阴性(0.758)。结论:CT平扫呈均匀性等/高密度或平扫密度不均匀、增强扫描后不均匀强化、伴发囊变、包膜征阴性可能是甲状腺微小FHN的特征性CT征象。Objective:To evaluate the CT features of thyroid micro follicular hyperplastic nodule(FHN).Methods:The clinical and CT data of 69 patients with micro FHN(FHN group,109 lesions)and 77 patients with papillary thyroid microcarcinoma(PTMC group,90 lesions)were collected.The non-enhanced CT density,enhancement pattern,cystic degeneration,edge interruption,envelope sign and calcification were analyzed and compared between the two groups,and the diagnostic efficiencies were evaluated.Results:There were statistical significances in the non-enhanced CT density,enhancement pattern,cystic degeneration,edge interruption,envelope sign and calcification between the two groups(all P<0.05).The CT features with high positive predictive value included homogeneous iso-or high-density on non-enhanced CT(1.000),inhomogeneous density on non-enhanced CT(0.894),inhomogeneous enhancement(0.804)and cystic degeneration(0.838).The CT feature with high negative predictive value was absence of envelope sign(0.758).Conclusions:Homogeneous iso-or high-density or inhomogeneous density on non-enhanced CT,inhomogeneous enhancement,cystic degeneration and absence of envolpe sign are the significant CT features in diagnosing micro FHN.
