- large, sharply demarcated cystic mass, displaying high signal intensity on both T1 and T2 (reflecting increased concentration of proteinaceous material or haemorrhage), markedly indenting/compressing the posteroinferior aspect of the urinary bladder. It shows no diffusion restriction on DWI or contrast enhancement on the post-contrast scan. From its posterolateral aspect emerge two tubular structures; one is identified as obstructed left ejaculatory duct and the other - an ectopic ureter
- the right seminal vesicle does not show any abnormality
- the urinary bladder is well-distended but compressed at its posteroinferior aspect, as aforementioned. It shows average wall thickness. No focal area of altered signal intensity in the wall or lumen of the urinary bladder. The perivesical fat shows average signal intensity
- the prostate is normal in size and shows a smooth outline and normal zonal anatomy and signal intensity. The periprostatic fat shows normal signal intensity
- the visualised bowel, including the rectum, shows normal MR morphology and signal intensity
- no significant pelvic lymphadenopathy
- no free fluid
Impression:
Known left-sided renal agenesis with abovementioned ipsilateral seminal vesicle cyst and dilatation of the ejaculatory duct comprise the Zinner syndrome triad.
