[Intrascrotal lithiasis: an infrequent finding?].
OBJECTIVE: To report on 10 additional cases of intrascrotal calculi and briefly review the literature and pathogenesis of this benign lesion. METHODS: 10 patients that had consulted for diverse testicular conditions were evaluated by ultrasound using the 7.5 MHz probe. RESULTS: All patients were found to have a hydrocele of a larger or smaller volume with a mobile hyperechoic focus that produced acoustic shadows. CONCLUSIONS: The ultrasound finding of intrascrotal calculi is becoming increasingly more frequent. In our view, this is due to the fact that more sonographic studies are currently performed. The possibility to diagnose this condition obviates the need for subsequent explorations or surgery.

[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.

Symptomatic solitary right renal vein aneurysm: a case report.
Renal vein aneurysms are very uncommon. Those located in the right side are exceptional. A symptomatic, solitary, voluminous aneurysm of the right renal vein in a 33-year-old man is reported. The lesion was diagnosed preoperatively as a renal tumor. The pathologic study of the nephrectomy specimen disclosed a thrombosed saccular aneurysm measuring 5.5 cm with marked medial atrophy of its wall. Recognition that a mass like this reported is of vascular origin is very important to avoid percutaneous biopsy which could be potentially hazardous; and for undertaking conservative prophylactic surgery. Renal venography is indicated for the diagnosis of these lesions.
