Bilateral ovarian hydatid disease--an unusual case.

Hydatid disease is caused by parasitic tapeworm Echinococcus. The larval stage of this parasite can thrive in many parts of the body, most frequently in the liver. Primary ovarian location is very rare. In our case the patient had bilateral ovarian cysts which on histopathological study was found to be hydatid cysts. Moreover one of the cysts was multilocular which is also unusual.
