Hydatid disease is an endemic disease in Turkey. It is located mostly in the liver. Primary peritoneal hydatid cyst is rare and the mechanism of this infection is unknown. Ultrasonography and computerized tomography are the main diagnostic tools in identifying hydatid cyst. Surgical treatment is mandatory. In this article we report a case of primary intraperitoneal pelvic cyst hydatid rupture in a 25 years old male who admitted to the emergency department with a history of abdominal pain. At operation, ruptured pelvic hydatid cyst was found and excised. Partial omentectomy was applied. Peritoeal cavity was lavaged with hypertonic saline solution. Medical theraphy with albendazole was started. The postoperative course of the patient was uneventful. In endemic regions, hidatid cyst should be thought in differential diagnosis of pelvic cyst.
