The germ cell tumors are the most common type of testicular malignant tumors (90%). About 30% are revealed by metastasis usually into the retroperitoneum, with clinically normal testis. Ultrasound reveals a bright echogenic focus into the testis which is typical, considering the clinical presentation, for a regressed germ-cell tumor and guides the side of the orchidectomy which allows to suppress a still active tumoral tissue which will not be eradicated by chemotherapy. Two typical cases with sonographic guidance are reported herein and confronted with the cases previously described in the literature.
生殖细胞肿瘤是最常见的睾丸恶性肿瘤类型（占90%）。约30%的病例通过转移被发现，通常转移至腹膜后，而睾丸临床检查正常。超声检查显示睾丸内有一个高回声病灶，鉴于临床表现，这对于退化的生殖细胞肿瘤来说是典型表现，并为睾丸切除术的一侧提供指引，该手术能切除仍有活性的肿瘤组织，而这种组织无法通过化疗根除。本文报告了两例超声引导下的典型病例，并与文献中先前描述的病例进行了对比。
