Background: Echinococcus granulosus is a cestode that causes hydatid cyst disease with its larval form. The disease is often located in the liver; however, it may also be seen in the lungs, kidneys, spleen, brain, bone and heart.
Case Report: A 38-year-old woman who had been operated on 4 years ago due to hydatid cyst disease located in the liver, presented at our clinic with pain in the epigastric and inguinal areas. The sonographic, serological and pathological evaluation of the patient leaded us to an uncommon presentation of hydatid cyst lodged in the ovarium.
Conclusions: This case is reported to draw attention to unusual localizations of the hydatic cyst.
