甲状腺微小乳头状癌(PTMC)的超声征象分析

Ultrasonic Analysis of Thyroid Micropapillary Carcinoma(PTMC)

目的:对PTMC的超声征象进行分析,提高其临床诊断效能。方法:选取2017年12月~2019年11月在本院治疗的82例PTMC患者(恶性组),共102个结节,同时,选取同期58例良性甲状腺结节患者(良性组),共68个结节。所有患者均接受彩色多普勒超声检查。结果:恶性组超声征象主要包括结节形态不规则(60.78%),边界不清楚(62.75%),以低回声为主(90.20%),纵横比≥1(98.04%),部分病灶有声晕(25.49%)、囊变(65.69%)、钙化灶(68.63%),血流分布以Ⅲ型为主(50.98%),与良性组对比差异明显(P<0.05)。结论:PTMC超声征象明显,在诊断时对存在上述超声征象的结节应提高警惕,恶性结节的风险较高。

Objective:To analyze the ultrasonic signs of PTMC and improve its clinical diagnosis efficiency.Methods:82 PTMC patients(malignant group)treated in our hospital from December 2017 to November 2019 were selected,with a total of 102 nodules;meanwhile,58 benign thyroid nodules(benign group)were selected in the same period,with a total of 68 nodules.All patients underwent color Doppler ultrasonography.Results:The ultrasonic manifestations of malignant group mainly includes the irregular nodules form(60.78%),the boundary is not clear(62.75%),and given priority to with low echo(90.20%),aspect ratio(98.04%),1 or more audio dizzy part lesions(25.49%),cystic change(65.69%),calcifications(68.63%),blood flow distribution is given priority to withⅢtype(50.98%),compared with benign group significant difference(P<0.05).Conclusion:The ultrasonic signs of PTMC are obvious,and the nodules with the above ultrasonic signs should be diagnosed with high vigilance,and the risk of malignant nodules is high.
