[Primary testicular tumor].

OBJECTIVE: To report a case of primary germ cell testicular tumor that spontaneously remitted after metastasizing to the retroperitoneum, leaving histologically characteristic lesions of a fused tumor. The characteristic testicular ultrasound findings that permitted the diagnosis are described. METHODS/RESULTS: A 21-year-old male consulted for a retroperitoneal mass. The testes were normal on palpation. The testicular ultrasound showed a hyperechoic area with an acoustic shadow suspected as being a tumoral cicatrix. The histological analysis after orchidectomy revealed a mixed non-seminomatous germ cell tumor. CONCLUSIONS: Testicular ultrasound evaluation should be performed on all patients with retrosperitoneal germ cell tumor and normal testes on palpation. In the case described, there was good correlation between the ultrasound and the histological findings.

Transrectal sonography in the assessment of vaginal pathology: a preliminary study.

PURPOSE: We assessed the value of transrectal sonography (TRUS) in the diagnosis of vaginal abnormalities. METHODS: Six women between 16 and 77 years old underwent TRUS with a biplanar probe equipped with 5-MHz axial sector and longitudinal linear transducers. Sagittal and axial images of the bladder, vagina, and urethra were obtained. Sonographic findings were compared with those from surgery. RESULTS: TRUS showed hematocolpos in 3 patients and cysts in 3 patients. Surgery confirmed the findings. Pathologic examination revealed 2 Gartner's cysts and 1 vaginal inclusion cyst. CONCLUSIONS: TRUS represents a valid diagnostic tool for the assessment of vaginal abnormalities because it accurately visualizes lesions and clearly shows anatomic relationships.

[Traumatic thrombosis of the renal artery].

The authors describe five cases of radiological diagnosis of traumatic thrombosis of the renal artery, paying special attention to the aortography as a positive source of information able to provide on its own a guide to rapid and correct treatment. Special reference is made to the positive errors of filling of the excretory duct in the I.V.U. in the said traumatic thrombosis; a picture which is well produced due to the existence of polar arteries or because the thrombosis is distal to the start of the capsulo-adrenal artery branch which may produce nephrograms due to perforating arteries.
