Primary uterine hydatidosis - A rare occurence

Hydatidosis is a zoonotic infection which commonly affects the liver and the lungs. Secondary sites of infection are reported, although rarely. Primary infection of the uterus is a very rare entity and presents as a clinical dilemma. We hereby, report one such case of primary uterine hydatidosis which was provisionally diagnosed as an ovarian mass and during surgery mimicked a degenerated fibroid of the uterus. Histopathological examination revealed the true diagnosis of a parasitic infection of the uterus most likely hydatidosis. High index of suspicion is needed in females presenting with cystic uterine or adnexal masses especially in females residing in endemic areas for echinococcus.
