目的:研究超声在甲状腺囊实性结节(Cystic thyroid nodules,CTN)良恶性诊断中的应用价值;方法:选取2014年6月-2015年5月于我院行超声诊断的CTN患者146例,均行彩色超声检查,察看甲状腺结节的形态、位置、最大径、纵横比(A/T)、边缘等特征;结果:经病理检查,恶性CTN发生率为19.32%,良性CTN发生率为80.68%,以病理检查结果为金标准,超声检查的误诊率为2.84%。恶性CTN多为A/T≥1(61.76%),良性CTN形状多为卵圆形(79.58%),恶性CTN边界多毛刺(67.65%),良性CTN边界多光滑(93.66%),恶性CTN内部多为实性(55.88%),良性CTN内部多为微囊成分(49.30%),上述良恶性CTN特征比较,均存在统计学意义(p<0.05);结论:内部回声多为实性,形态较不规则,呈毛刺或微小分叶状,A/T≥1、低回声、极低回声为恶性CTN的重要超声特征。
Objective: To study the value of ultrasound in the diagnosis of benign and malignant thyroid thyroid nodules (CTN). Methods: 146 patients with CTN diagnosed by ultrasound in our hospital from June 2014 to May 2015 were enrolled in this study. Color ultrasound examination was performed to observe the features of thyroid nodules such as shape, location, maximum diameter, aspect ratio (A / T) and margins. Results: The pathological examination showed that the incidence of malignant CTN was 19.32%, and the incidence of benign CTN was 80.68 %, The pathological examination results as the gold standard, misdiagnosis rate of ultrasound was 2.84%. Malignant CTN mostly A / T≥1 (61.76%), benign CTN shape oval (79.58%), malignant CTN border burr (67.65%), benign CTN border more smooth (93.66%), malignant CTN (55.88%) were mostly solid microencapsule (49.30%) in benign CTN. There were significant differences between benign and malignant CTN (p <0.05) .Conclusion: Most internal echoes are solid, More irregular, burr or tiny lobular, A / T ≥ 1, low echo, low echo is an important ultrasound features of malignant CTN.
