Material and Method: All of the patients were anal-ysed retrospectively for age, gender, symptoms, lession localization and sur-gical procedure. We compared our results with existing literature. Results: Our report concerns 73 patients who were aged 6-73 (mean 38,2) years and include 37 male, 36 female. The mostly clinical manifestation was cough. Pulmonary hydatid cysts had been seen in the rigt lower lob most frequently. The most choosen surgical prosedure was cystotomy and capitonnage with posterolateral thoracotomy. Median sternotomy was performed for a patient who had perikardial hydatic cysts. For the liver cysts located on the dome of the liver with pulmonary hydatic cysts, we performed transthoracic approach with rigt thoracotomy and phrenotomy. Discussion: Pulmonary hydatidosis is stil a serious health problem in developing countries. It must be kept in mind in the endemic areas for excluding the other diagnosis. The patients who had diagnosis as pulmonary or liver hydatic cysts must be investigated for the both organs. The primary treatment Surgery is being done with low mortality and morbidity in patients with pulmonary hydatid disease.
