甲状腺低回声结节的超声造影表现与病理对照分析

Characteristics of thyroid hypoechoic nodules with contrast-enhanced ultrasound: compared with pathological findings

目的探讨甲状腺低回声结节的超声造影(Contrast-enhanced Ultrasound,CEUS)增强模式。方法回顾性分析111个甲状腺低回声结节的超声造影模式,观察造影的增强模式,并与术后病理对照。结果病理证实恶性结节68个,良性结节43个。恶性结节超声造影表现以不均匀增强为主(55/68),良性结节多表现为环状增强(28/43)。结论超声造影有助于甲状腺低回声结节的良恶性的鉴别诊断。

Objective To observe the enhancement patterns of benign and malignant thyroid hypoechoic nodules. Methods The ultrasonic diagnosis of 111 thyroid hypoechoic nodules was retrospectively analyzed. The enhancement patterns were recorded and were compared with the pathological results. Results The pathological results demonstrated that 68 nodules were malignant and 43 were benign. Most malignant nodules showed inhomogeneous enhancement in the ultrasonic results（ 55 /68）,while most benign ones showed ring enhancement（ 28 /43）. Conclusion Contrast-enhanced ultrasound is helpful to differentially diagnose benign and malignant thyroid hypoechoic nodules.
