摘要

目的探讨超声造影在睾丸占位性病变良恶性鉴别诊断中的价值。方法回顾性分析我院术后经病理证实的81例睾丸占位性病变患者（81个病灶）的超声造影特征

对病灶的增强边界、始增速度、增强后病灶范围、增强均匀程度、增强水平、廓清速度6个超声造影特征进行分析

比较良恶性睾丸占位性病变的超声造影特征;应用多因素二元Logistic回归分析各项超声造影特征预测睾丸占位性病变的恶性风险程度。结果 14个良性病灶超声造影表现为无增强

余67个病灶均有增强

其中良性31个

恶性36个。睾丸良恶性占位性病变的增强边界、始增速度、增强后病灶范围比较差异均有统计学意义（均P<0.05）

增强均匀程度、增强水平、廓清速度比较差异均无统计学意义。多因素二元Logistic回归分析筛选出3个与睾丸恶性占位性病变相关的超声造影特征

其相对恶性风险程度由高到低依次为:增强边界不清、快进、增强后病灶范围增大（OR=23.188、14.976、10.554

均P=0.000）。结论超声造影对鉴别睾丸占位性病变的良恶性具有重要价值。

Abstract

ObjectiveTo explore the value of contrast-enhanced ultrasound（CEUS）in the differential diagnosis ofbenign and malignant testicular lesions.MethodsThe CEUS characteristics of 81 cases of testicular lesions confirmed bysurgical pathology in our hospital were analyzed retrospectively. Six CEUS characteristics of the benign and malignant testicularlesions were analyzed.The six characteristics were as follows:the boundary of enhancement

the speed of wash-in

the size of thelesion after enhancement

the homogenicity of enhancement

the intensity of enhancement

and the speed of wash-out.Binarymultivariate Logistic regression was used to analyze the malignant risk of each CEUS characteristic in predicting the testicularlesions.ResultsFourteen benign lesions showed no enhancement on CEUS

the remaining 67 lesions showed enhancement

including 31 benign and 36 malignant lesions.The boundary of enhancement

the speed of wash-in

and the size of the lesionafter enhancement were statistically different in benign and malignant testicular lesions（all P<0.05）.There were no statisticallysignificant difference in the homogenicity of enhancement

the intensity of enhancement

and the speed of wash-out. Binarymultivariate Logistic regression analysis screened three CEUS characteristics related to malignant lesions.The relative malignantrisk from high to low is as follows:ill-defined enhanced border

fast wash-in

enlarged size after enhancement（OR=23.188

14.976

10.554

all P=0.000）.ConclusionCEUS is of great value in the differential diagnosis of benign and malignant testicular lesions.
