Inguinal bladder hernia is a rare clinical condition, with 1–3% of all inguinal hernias involving the bladder. Any portion of the bladder may herniate, from a small portion or a diverticulum to most of the bladder. We present a 55-year-old male with an intermittent right scrotal mass of 6 months’ duration. The mass lesion protruded through the right inguinal canal before voiding and reduced after that. Scrotal sonography revealed a hypoechoic lesion in the scrotum that stretched cranially to the intra-abdominal portion of the bladder. Excretory urography showed a duplicated system in the left kidney and deviation of the left orifice to the right side of the trigon. Finally, cystography illustrated herniation of the bladder to the right scrotum. Surgical repair of the hernia was done with mesh. Follow-up cystography one month postoperatively revealed no herniation.
