Ejaculatory duct cysts are a rare type of prostatic cysts. We report 3 cases of symptomatic ejaculatory duct cysts which have been explored by MR imaging. The MR findings were round or oval masses, medial or paramedial in the prostatic gland above the level of the verumontanum, extending into the prostatic base. They displayed a low signal intensity on T1-weighted images and high signal intensity on T2-weighted images (2 cases) or high signal intensity on both T1- and T2-weighted images (1 case). The diagnosis was confirmed by an ultrasonographically guided transperineal aspiration demonstrating spermatozoa in the cyst fluid.
射精管囊肿是一种罕见的前列腺囊肿类型。我们报告3例有症状的射精管囊肿，均经磁共振成像（MR）检查。MR表现为圆形或椭圆形肿块，位于前列腺中叶或中叶旁，在精阜水平上方，延伸至前列腺底部。在T1加权像上呈低信号强度，在T2加权像上呈高信号强度（2例），或在T1加权像和T2加权像上均呈高信号强度（1例）。经超声引导经会阴穿刺抽吸，囊肿液中发现精子，从而确诊。
