Hydatid cysts in a pregnant uterus.

Hydatid cystic disease is a parasitic disease caused by the larval form of Echinococcus granulosus. Canines are the definitive host, while affected human beings are the accidental host [1, 2]. Hydatid cysts may be found in almost any part of the body, but are most often found in the liver (60 %) and lungs (30 %). The occurrence of hydatid disease is extremely low in genital organs, appearing with an incidence of 0.5 %. The incidence of hydatid disease in pregnancy is very rare, ranging from 1/20,000 to 1/30,000. There are only few reports of obstructed labor caused by a pelvic hydatid cyst. We are reporting the first case in the literature where hydatid cysts primarily involving the pregnant uterus were managed by delivering a live fetus by cesarean section followed by complete resection of the hydatid cysts.
