结节性甲状腺肿和甲状腺腺瘤的超声诊断及鉴别诊断

目的 分析结节性甲状腺肿和甲状腺腺瘤的声像图表现,探讨超声对二者的鉴别诊断价值.方法 分析32例甲状腺腺瘤和49例甲状腺结节患者的声像图特点,并与术后病理对照.结果 二维声像图示:结节性甲状腺肿表现为多结节分布,占68.7%(22/32),且周边少见晕环,腺体实质同声增粗;甲状腺腺瘤表现为单结节分布,占31.2%(10/32),且周边多见晕环,实质回声均匀.CDFI示:两者结节周边及内部血流信号有显著性差异(P＜0.05).结论 彩色多普勒超声可提高结节性甲状腺肿和甲状腺腺瘤的鉴别诊断水平,具有重要的临床意义.

Differential diagnosis of nodular goiter and thyroid adencma with sonography

Objective To evaluate the differential diagnostic value of sonography in nodular goilter and thyroid adenoma. Methods The sonographic characteristics of 32 cases with nodular goilter were compared with those of 49 cases with thyroid adenoma; all selected patients were confirmed by postoperative pathologic results. Results Two-dimensional ultrasonographic results were as follow: the ultrasonographic findings in nodular goilter included multinodular distribution (22/32, 68.7%), fewer halos around and hyperechoic gland but the thyroid adenoma were solitary (10/32,31.2%), more halos around and well-distributed echoic gland. Color Doppler flow imaging found that the perimeter and internal signals between nodular goiter and thyroid adenoma had significant difference (P<0.05). Conclusion Color Doppler sonography has important clinical value in differential diagnosis between nodular goiter and thyroid adenoma.
