Primary pelvic hydatidosis: About two cases

Primary pelvic hydatidosis in women is a rare or even exceptional entity; its diagnosis is often late.

We report two cases of pelvic hydatid cyst with a clinical picture simulating an ovarian tumor, dignosticated at the Mohamed VI Center for the treatment of gynecomammary cancers in Casablanca.

Pelvic hydatidosis is rare; its incidence is between 0.30 and 5.27% of hydatid localizations. Its diagnosis is exceptionally made preoperatively; the patient is most often consulted for pelvic pain, which reveals the presence of an abdominopelvic mass. Pelvic ultrasound is the first-line examination. Serology is necessary only in doubtful cases. Treatment is essentially surgical and must take into consideration the desire for pregnancy in women of childbearing age.

The vital and gynaecological prognosis is at stake and early diagnosis is necessary. This diagnosis should always be evoked when there are signs of pelvic damage, despite the rarity of hydatid cysts in this location. However, prevention remains the best solution to this scourge, especially in endemic areas.
