未成年人睾丸肾上腺残基瘤的超声表现

Testicular adrenal rests tumor: sonographic features

目的总结未成年人睾丸肾上腺残基瘤(TART)的超声表现。方法回顾性分析中山大学附属第一医院经手术病理或临床确诊的13例未成年人TART的超声表现。分析内容包括受累睾丸数目及形态、大小、睾丸纵隔有无受累;病灶位置、生长方式、形态、边界、包膜、大小、内部回声、血供等指标。结果 13例TART均为双侧睾丸同时发病,共26个病灶,其中5例(5/13,39%)患者的睾丸大小及形态均正常,8例(8/13,62%)患者睾丸增大;12例(12/13,92%)患者睾丸内可见睾丸纵隔回声;26个(26/26,100%)TART均呈局限性生长,位于睾丸门或睾丸纵隔旁,21个(21/26,81%)病灶形状不规则,5个(5/26,19%)病灶呈类圆形;26个(26/26,100%)病灶均边界清楚,未见包膜回声;病变大小为(1.5±1.0)cm;13个(13/26,50%)病灶呈均匀低回声,11个(11/26,42%)病灶呈不均质低回声,2个(2/26,8%)病变呈不均质等回声;19个(19/26,73%)病灶血供丰富,7个(7/26,27%)病灶血供稀少。结论未成年人TART双侧发病、低回声围绕睾丸纵隔生长的超声表现具有特征性,超声检查具有重要的临床意义。

Objective To evaluate the sonographic features of testicular adrenal rests tumors in minor males. Methods The sonographic feature of pathologically or clinically confirmed testicular adrenal rests tumor in 13 minor males was retrospectively analyzed;we analyzed the number, morphology and size of affected testis; the involvement of testicular mediastinum; lesion location; the growth pattern, shape, boundaries, size, internal echo and blood supply of lesions. Results All of the 13 cases were bilateral and there were 26 lesions in all, 5 cases （5/13, 39%） had normal testicular size and morphology, testicular mediastinum were seen in 12 cases （12/13, 92%）;26 （26/26, 100%） TARTs were all located near the testicular mediastinum or the testis hilar;21 （21/26, 81%） lesions had irregular shape while 5 （5/26, 19%） lesions were round;26 （26/26, 100%） lesions all had clear boundary but had no echo envelope;the lesion size was （1.5 ± 1.0） cm in average;13 （13/26 , 50%） lesions showed homogeneous hypoecho, 11 （11/26, 42%） lesions showed inhomogeneous hypoecho and 2 （2/26, 8%） lesions showed inhomogeneous isoecho; 19 （19/26,73%） lesions displayed rich blood supply and 7 （7/26, 27%） lesions displayed scarce blood supply. Conclusion The sonographic appearance of TART in minor males was characteristic, ultrasonography has important clinical value.
