摘要
目的观察睾丸混合性生殖细胞瘤(TMGCT)的超声表现。方法回顾性分析我院经手术病理证实的48例TMGCT的超声表现。结果 48例中,22例肿瘤位于左侧睾丸,26例位于右侧睾丸。17例伴腹膜后淋巴结转移,9例伴肺转移,5例伴腹股沟区淋巴结转移,2例伴肝转移,2例伴纵隔转移,1例伴颈部淋巴结转移。28例超声可见睾丸内囊实混合回声病灶,18例低回声病灶,2例稍强回声病灶。38例肿瘤边界不清晰,10例边界清楚;29例肿瘤形态规则,19例形态不规则。CDFI示46例肿瘤内可见彩色血流信号。结论 TMGCT的超声表现有一定的特征性,可为诊断提供影像学依据。
Objective To observe manifestations of testicular mixed germ cell tumor(TMGCT)in conventional ultrasound.Methods Imaging features of histopathologically proved TMGCT in 48 patients were retrospectively analyzed.Results Among the 48 patients,the tumors located in left testis(n=22)and right testis(n=26),respectively.Retroperitoneal lymph node metastasis was found in 17 patients,lung metastasis was found in 9 patients,inguinal lymph node metastasis was found in 5 patients,liver metastases was found in 2 patients,mediastinal metastasis was found in 2 patients,and cervical lymph node metastasis was found in 1 patient.Mixed-echogenic(n=28),hypoechoic(n=18)and hyperechoic(n=2)were shown by ultrasound.Ill-defined boundary was found in 38 patients,and well-defined boundary was found in the other 10 patients.Regular shape was found in 29 patients,while irregular shape was found in 19 patients.CDFI showed abundant tumor blood flow signals in 46 patients.Conclusion The ultrasound manifestation of TMGCT has certain characteristics and can provide imaging basis for diagnosis.
