目的 探讨类实性低回声结甲结节的常规超声和超声造影的表现及其诊断价值。方法 回顾性分析经细胞学或手术病 理证实的35个低回声结甲结节的常规超声和超声造影检查特征。结果 低回声、血流不丰富、超声造影以无增强为 主是类实性低回声结甲结节的主要特征，病理显示类实性区为出血囊性变。结论 不典型低回声结甲结节的诊断， 需以超声二维表现为基础，结合彩色多普勒超声表现和超声造影检查，提高诊断符合率。

Objective To discuss the findings and the diagnostic values of conventional ultrasound and contrast enhanced ultrasound of like-solid hypoechoic nodular goiter nodules. Methods Analyze retrospectively the characteristics of conventional ultrasound and contrast enhanced ultrasound of 35 like-solid hypoechoic nodular goiter nodules, which were confirmed by cytology or surgical pathology. Results The main characteristics of like-solid hypoechoic nodular goiter nodules include hypoechogencity , hypovascular and no enhanced in contrast enhanced ultrasound. The likesolid area is hemorrhage cystic change in pathology. Conclusions Diagnosis of the atypical hypoechoic nodular goiter nodules should be based on B mode ultrasound, color Doppler ultrasound , and contrast enhanced ultrasound to improve the diagnosis.
