Pelvic genital hydatid disease is rare. It accounts for only 0.9% of hydatidoses and 1.8% of operated adnexial masses. Its clinical signs are often misleading, making the preoperative diagnosis difficult. This diagnosis rests on questioning with particular attention to the socio-professional context and previous history of hydatid disease. Ultrasonography is the first choice examination. Treatment is purely surgical, the best technique being total cystectomy, but the best treatment is prevention.
