title: [Primary retroperitoneal hydatid cyst].
abstract: OBJECTIVE
  To review the pathogenesis, clinical features and treatment of a rarely observed site of presentation of hydatid cyst.
  
  
  RESULTS
  A case of an isolated retroperitoneal hydatid cyst is presented. Diagnosis was based on the immunodiagnostic test and radiological examination. Treatment was by surgery.
  
  
  CONCLUSIONS
  Isolated retroperitoneal hydatic cyst is rare. The abdominal mass is the most frequent sign, and less frequently, concomitant compressive syndrome. Diagnosis is based on the biological examinations, percutaneous puncture and radiological findings. Treatment is by surgery. Azoles are useful for intraoperative ruptured cysts and to reduce the risk of recurrence.
