Abdominal and pelvic hydatid cyst obstructing the labor

Hydatid cystic disease is a parasitic disease primarily infesting the sheep and cattle. It is a rare condition in pregnancy with an incidence of 1/20000 pregnancies. An eighteen-year-old primigravida was evaluated due to obstructed labor. Multiple abdominal and pelvic hydatid cysts were diagnosed by ultasonography and a healthy infant with birthweight of 3330 g was delivered by cesarean section. While the cysts situated on the posterior uterine wall, paraovarian region and omentum were removed totally, the hepatic cysts were only partially removed and then drained. The hydatid disease should be considered in differential diagnosis of adnexal masses obstructing the labor in pregnancy (Fig. 3, Ref. 9).
