A 74-year-old female with the chief complaint of lower abdominal and anal pain had been suffering from total incontinence due to cerebral palsy since her childhood. A giant stone was palpable on vaginal examination. A radiograph showed a giant calcification in the pelvis. Magnetic resonance imaging (MRI) revealed a giant vesico-vaginal stone, which occupied most of the bladder and vagina. Cystolithotomy was performed. The removed stone weighed 435 g, and measured 9.0 x 6.5 x 5.5 cm, and was composed of magnesium ammonium phosphate. To our knowledge only eight cases of female giant vesical stone have been reported. We herein report a rare case of vesico-vaginal stone unrelated to gynecological procedures.
