title: [Ultrasonic diagnosis of non-palpable germinal tumors of the testis. Apropos of 2 cases].
abstract: 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.
