目的：探讨Zinner综合征的影像特征。方法回顾性分析经临床诊断的8例Zinner综合征患者资料，行腹、盆腔CT和（或） MR检查，分析其影像特征。结果8例患者腹、盆腔CT和（或） MR上均表现为一侧肾缺如并同侧精囊囊肿，其中右侧3例，左侧5例。精囊囊肿最大径为4.2～7.0 cm，为类圆形且边界略不规则，或呈明显囊管状扩张。 CT平扫囊肿内部为低密度。 T1 WI低或高信号，T2 WI高信号。6例压迫膀胱后壁，2例囊肿内部见液-液平面，1例精囊区见残存输尿管结构，均未合并其他泌尿生殖系异常。结论 Zinner综合征的影像表现具有特征性，应重点观察精囊囊肿。

Objective To explore imaging features of Zinner syndrome.Methods Eight male patients with clinically diagnosed Zinner syndrome performed abdominal and pelvic CT and /or MRI scan.The radiological data was studied retrospectively.Results Eight cases showed seminal vesicle cyst with ipsilateral renal agenesis on CT and/or MR imaging ( left side, n =5; right side, n =3).The maximal diameter of seminal vesicle cysts varied from 4.2 to 7.0 cm, and appeared as oval cystic lesion with irregular contour or tube-like dilatation , which appeared low density on CT image and hypo-or hyperintensity on T 1 WI and hyperintensity on T 2 WI.Bladder compression was found in 6 cases.Fuild-fuild level in the cysts was seen in 2 cases.Remnants of ureter structure were seen in only 1 case.There was no other accompanying abnormality of urinary system.Conclusions Zinner syndrome presents with characteristic imaging features , and the key issue is differential diagnosis of seminal vesicle cysts.
