We present a case of a urothelial neoplasm arising within a direct bladder
hernia in the inguinal canal. Bladder hernias are rarely found preoperative
ly and are exceptional sites of neoplasm. Spiral computed tomography with g
aseous insufflation of the bladder demonstrated the bladder hernia and the
extension of the neoplasm in the inguinal canal more accurately than other
computed tomographic techniques with nonopacified and iodinated urine.
