title: Dilatation of the rete testis: ultrasound study.
abstract: The aim of this study was to show the US findings in mode B and color Doppler duplex of the dilatation of the rete testis, in order to analyze its association with other scrotal processes and to confirm their inclusion into the benign testicular lesions. We present seven diagnosed cases (mean age 61 years) of dilatation of the rete testis to which a clinical control and US was accomplished up to 1 year. The scrotal sonography study was carried out with a linear probe of 7.5 Mhz. In the US examination we observed in all cases an intratesticular image located in the mediastinum testis constituted by anechoic and serpiginous tubular structures, which do not show any blood flow with the color Doppler. In one case the mentioned observations were bilateral. Five cases had cysts in epididymis and the last case showed an increase in size in the epididymis head. Color Doppler duplex examination did not detected flow dots in the seven patients. The dilatation of the rete testis is a benign entity frequently associated with pathology in epididymis, with specific US findings which permit avoidance of invasive tests.
