摘　　要：目的探讨睾丸间质细胞瘤(LCT)的超声特征及误诊原因,以期为LCT临床诊疗提供客观依据。方法回顾性分析13例经病理证实为LCT的临床及超声声像图特点,并与同期确诊的32例睾丸精原细胞瘤对照分析。结果本组13例LCT均为交界性;病灶均为单发,平均最大径(1.79±1.01)cm,其中8例(8/13)位于睾丸边缘;5例呈圆形或卵圆形,8例呈分叶状;11例边界清晰,2例边界不清晰;4例呈均匀低回声,7例呈不均匀低回声,2例呈混合回声。12(12/13)例瘤体内部及周缘探及丰富血流信号,其中6例血流分布呈"向心性"。本组LCT与睾丸精原细胞瘤的发病年龄、瘤体最大径差异有统计学意义(P<0.05),余超声表现均无统计学差异(P>0.05)。术前超声检查,2例考虑LCT,余11例均误诊(其中6例误诊为精原细胞瘤)。结论典型LCT的超声表现具有一定特征,结合相关临床资料(如年龄、性激素水平等)可提高其术前诊断准确率,指导临床决策。Objective To investigate ultrasound characteristics and misdiagnosis of testicular leydig cell tumor(LCT),and to provide evidence for clinical diagnosis and treatment of LCT.Methods The clinical and ultrasonographic features of 13 patients with LCT confirmed by pathology were retrospectively analyzed,and the results were compared with 32 patients with testicular seminoma confirmed in the same period.Results 13 cases of LCT in this study were all borderline.The lesions were single,with the average diameter of(1.79±1.01)cm.Eight cases(8/13)were located at the edge of testis.5 cases were round or oval,and 8 cases were lobulated.11 cases had clear boundary,and 2 cases had unclear boundary.4 cases showed homogeneous hypoechoic,7 cases showed inhomogeneous hypoechoic,and 2 cases showed mixed echo.In 12(12/13)cases,rich blood flow signals were detected inside and around the tumor,and the blood flow distribution was“centripetal”in 6 cases.The age of onset and the maximum diameter of tumor between LCT and testicular seminoma in this study were statistically significant(P<0.05);while there was no significant difference in the other ultrasonic features(P>0.05).With preoperative ultrasonography,2 cases were considered as LCT,the remaining 11 cases were misdiagnosed(6 cases were misdiagnosed as spermatogonia).Conclusions The ultrasonic manifestations of LCT have certain characteristics.Combined with relevant clinical data(such as age,sex hormone level,etc.)can improve the accuracy of preoperative diagnosis and provide help to clinical decision-making.
