Hydatid disease is a considerable social health problem because of its endemic distribution in many countries. It is a cosmopolitan parasite. It is a parasitic disorder caused by Echinococcus granulosus. The human is an accidental host of the parasite. Mostly, hydatid cyst is primarily in liver (75%) and lung (15%). Intraperitoneal hydatid cyst is found in 13% and it is usually secondary to rupture of primary hepatic cyst. In the literature fewer than 10 cases of the primary omental hydatid cyst are reported till date. We represent the case of 29 year old female having the torsion of the primary intraperitoneal hydatid cyst with review of literature.
