目的探讨高频超声对小儿甲状腺肿瘤的应用价值。方法回顾性分析12例小儿甲状腺肿瘤的声像图特征,并与病理诊断结果对照。结果甲状腺腺瘤9例,甲状腺癌3例。两者在径线比值,形态,内部回声,内部血流,颈部淋巴结肿大等方面略有差别。结论高频超声检查对小儿甲状腺肿瘤的诊断和鉴别诊断有重要临床应用价值。 Objective To investigate the value of high frequency ultrasound in pediatric thyroid tumors. Methods Retrospective analysis of 12 cases of pediatric thyroid tumors sonographic features and pathological diagnosis of the control. Results 9 cases of thyroid adenoma, 3 cases of thyroid cancer. The two in the radial ratio, morphology, internal echo, internal blood flow, cervical lymph node enlargement and so on slightly different. Conclusion High-frequency ultrasound in pediatric thyroid tumors diagnosis and differential diagnosis of important clinical value.
