Testicular sonograms were performed in four patients with pathologically proven metastatic neoplasms but a normal physical examination of the scrotum. An abnormal echo texture was seen in all cases: focal hypoechoic nodule (about 1 cm) in two, diffusely hypoechoic in one, and mixed diffuse/focal abnormality in one. Correct sonographic identification of the abnormal testis facilitates surgical removal and precludes unnecessary excision of the contralateral normal testes. The authors recommended testicular sonography to be used as a routine procedure in all patients with such a clinical presentation.
对4例经病理证实有转移性肿瘤但阴囊体格检查正常的患者进行了睾丸超声检查。所有病例均可见异常回声纹理：2例为局灶性低回声结节（约1 cm），1例为弥漫性低回声，1例为弥漫性/局灶性混合异常。正确的超声识别异常睾丸有助于手术切除，并避免不必要地切除对侧正常睾丸。作者建议将睾丸超声检查作为所有有此类临床表现患者的常规检查方法。
