title: [Extra-pulmonary thoracic hydatid cysts].
abstract: OBJECTIVE
  To report our experience in the management of intra-thoracic extra-pulmonary hydatid cyst, and to discuss the etio-pathogeny of this affection.
  
  
  METHODS
  Among 80 patients who underwent surgery in our department for intra-thoracic hydatid cysts between September 2001 and September 2005, six patients (7.5%) had an extra-pulmonary localization. There were 4 men and 2 women with a mean age of 43 years. The lesions were pleural, diaphragmatic or mediastinal. Thoracotomy was performed in all patients.
  
  
  RESULTS
  One patient had multiple localizations (diaphragm, anterior mediastinum and pleura). The cyst was simple in 5 cases and complicated (rupture) in one case. The diagnosis of hydatid cyst was suspected on the basis of the radiological data and confirmed intra-operatively. No complications or recurrences were observed during the follow-up period.
  
  
  CONCLUSIONS
  Intra-thoracic extra-pulmonary hydatid cyst is uncommon even in endemic countries such as Morocco. Surgery is the best treatment and must be proposed early in order to prevent complications. Medical treatment is reserved for complicated forms.
