Abstract: 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.
