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.
本研究的目的是展示睾丸网扩张在B型超声和彩色多普勒双功超声检查中的表现，以便分析其与其他阴囊病变的关联，并确定其是否属于良性睾丸病变。我们报告了7例经诊断的睾丸网扩张病例（平均年龄61岁），对其进行了长达1年的临床对照和超声检查。阴囊超声检查使用7.5兆赫兹的线性探头。在超声检查中，我们在所有病例中均观察到位于睾丸纵隔内的睾丸内图像，由无回声且呈蜿蜒状的管状结构组成，彩色多普勒检查显示无血流信号。其中1例上述表现为双侧性。5例附睾有囊肿，最后1例附睾头部增大。彩色多普勒双功超声检查在这7例患者中均未检测到血流信号。睾丸网扩张是一种良性病变，常与附睾病变相关，具有特定的超声表现，可避免进行侵入性检查。
