A45-year-old man presented with sciatica. Magnetic resonance imaging (MRI) of his lumbosacral spine revealed an gram benign prostate noted.
-

vealed an absent right kidney, dilated right ureter and seminal vesicle, and a normal left renal tract (Figure 1). T1 and T2-weight-
ed MRI with gadolinium again demonstrated right renal agenesis, a dilated, non-obstructed right ureter containing proteinaceous 
material with no vesical connection, and a dilated right seminal vesicle (Figures 2 and 3). 
Cystic dilatation of the right seminal vesicle associated with right renal agenesis and a prostatic utricle cyst has been described 
in a patient presenting with lower tract symptoms.(1) Incidental detection of seminal vesicle cysts, renal agenesis, and ectopic 
ureter has been documented in asymptomatic patients presenting for prostatic biopsy.(2) Laparoscopic removal of cystic seminal 
vesicles and an aplastic renal moiety with associated ectopic megaureter has been described.(3)
