title: Unusually located hydatid cysts: intrathoracic but extrapulmonary.
abstract: BACKGROUND
  Hydatid cyst disease is still a problem in Turkey, as well as in many other places in the world. Extrapulmonary location of the disease in the thorax is very rare, and surgical procedures can be considered that differ from those used for pulmonary hydatid cysts.
  
  
  METHODS
  We reviewed retrospectively our experience in the surgical treatment of 22 patients with intrathoracic, extrapulmonary hydatid cysts. In our department, 297 patients with thoracic hydatid cysts were managed surgically in the last 14 years, in 22 (7.4%) of whom the cysts were localized extrapulmonarily in the thorax. The locations of these hydatid cysts were a fissure, the pleural cavity, chest wall, mediastinum, myocardium, and diaphragm.
  
  
  RESULTS
  Total resection was chosen as the surgical procedure in all patients except 4 (18.2%), 1 of whom had cystectomy and capitonnage for cardiac hydatid cyst and 3 of whom had cystectomy and local curettage for cysts located in the chest wall. Empyema developed postoperatively in 1 case (4.5%) with a cyst in the fissure. The follow-up period was 1 year, and there were no deaths.
  
  
  CONCLUSIONS
  Hydatid cyst may be found in many different sites, including extrapulmonarily in the thorax, and bearing this in mind will facilitate planning of the operation.
