[Infiltrating tubo-ovarian abscess in IUD-associated actinomycosis]

We report on a case of a 55-year old patient with a great adnexal tumour (10 x 5 x 8 cm), on the left side with infiltration of the bladder and the pelvis with recurring urinary retention in the kidney. Histological examination revealed an intrauterine device-associated actinomycosis. Following a 6-month high dose penicillin therapy, the abdominal hysterectomy with adnexectomy and partial resection of the bladder with new implantation of the ureter (Boari) was performed. The postoperative period was uneventful, the urogram normal.
