A fluid collection within the right ischioanal fossa is seen with external opening within the right natal cleft, likely origination from the blind ending end-to-side anastomosis.
However, an asymmetry is seen within the seminal vesicles, with the left seminal vesicle larger and with lower signal intensity than the right one.
The sagittal images demonstrate a tract between the colon and left seminal vesicle. (series 3-8)
The axial images confirm the presence of a colonic-seminal vesicle fistula.
