We present a case of bilateral ectopic vas deferens with insertion in the posterior bladder, a rare congenital anomaly related to abnormal distal Wolffian duct development. Common presentations include urinary tract infections, epididymitis or a swollen scrotum although this abnormality can be an asymptomatic, incidental finding. There is also a strong association with anorectal malformations, ureteral ectopia and vesicoureteral reflux.
