過去の卵巣腫瘍茎捻転が長期経過で膀胱瘻を形成したと思われた１例

抄録

　We report the case of a 70-year-old woman who presented with chronic severe abdominal pain, possibly caused by a torsion that developed into a fistula between a tumor and her bladder after an ovarian tumor torsion. The patient noted the development of pyuria, unresolved by antibiotics. Cystoscopy revealed a torose lesion in the bladder, and magnetic resonance imaging revealed bilateral ovarian teratoma and bladder penetration. Gynecologists and urologists performed a laparoscopic surgery. Intraoperatively, the greater omentum adhered to the bilateral ovarian tumors and torsion of the ovarian tumor pedicle. We performed a bilateral adnexectomy, with partial cystectomy under cystoscopy control. Pathological examination revealed mature ovarian teratomas, with inflammation on the bladder wall.
