title: [Ultrasonic diagnosis of so-called "occult" testicular tumor].
abstract: A 40-year old man complaining of severe pain in the right mid-abdomen, nausea and vomiting was brought to the casualty department. Sonography revealed retroperitoneal masses in the right mid-abdomen and the left lower abdomen. These masses were confirmed by computed tomography and lymphography to be lymph node metastases. In the smaller right testis, in which a tumour was not suspected, a hypoechoic region was identified, which on histological examination after orchiectomy proved to be a pure seminoma.
