Primary Ovarian Hydatid Cyst – An Extremely Rare Case

Abstract

Primary Ovarian hydatid disease is rare entity, produced by larval stage of echinococcus granulosus. Hydatid disease commonly involves Liver, Lung, abdominal cavity, spleen and infrequently in pelvic organs, ovary and uterus. Primary hydatid cyst of the ovary is an extremely rare presentation. Many cases are not symptomatic and may be discovered accidentally. In 80 % of cases reported with a cyst in this location, the ovary is the most common affected organ followed by uterus. Primary ovarian hydatid cysts are very rare and can be primary as well as secondary in nature. This condition is misdiagnosed in the majority of cases and may be mistaken for ovarian cysts or cystic tumour of the ovary and the symptoms are usually non-specific. We are reporting an extremely rare case of primary ovarian hydatid cyst in a 35 years old lady, complaining of pain in abdomen and abdominal lump. Ultrasonography revealed a left side large ovarian cyst and after laparotomy revealed an ovarian hydatid cyst in the left ovary, which was confirmed by histopathology examination.
