Abstract
Introduction: Bronchogenic cysts are rare congenital lesions which originate from ventral foregut and most commonly originated in the central mediastinum. They rarely have symptoms and at the time of diagnosis they usually are large, infectious or complicated. In this study a case report of bronchogenic cyst is reported. Case: The patient to be presented is a 47 years old man with sudden onset of chest pain, severe dyspnea, tachypnea and decreasing right lung sounds. Symptoms of pneumotorax were observed in lung radiography. The patient was treated by inserting chest-tube, but there was no response to the treatment. Urgent thoracotomy was performed. A large single bronchogenic cyst was detected in the right lung parenchyma attached to intermediate bronchus. Complete resection was performed. According to the pathology report, pneumothorax was developed secondary to rupture of the bronchogenic cyst. Conclusion: Lung parenchyma is not a common area for developing bronchogenic cyst but it has special importance because of it's severe complications. Since exact diagnosis is not always possible before surgery, it is necessary to perform resection in all suspicious cases.

Abstract
Background: Central venous catheterization (CVC) is a common procedure associated with various side effects such as pneumothorax. Recently, the routine post-catheterization chest X-ray has been challenged. The aim of the present study was to design a scoring system for selecting patients requiring radiography after CVC procedure. Materials and Methods: In this cross-sectional study, 210 patients requiring CVC were enrolled in the study and pneumothorax potential risk factors, including body mass index>30, history of neck or chest surgery, emphysematous disease, history of catheterization, number of punctures, inappropriate position during CVC, and treatment with ventilator were recorded. Finally, chest radiography and clinical signs before and after CVC were compared and scoring system sensitivity and specificity were determined. Results: Incidence of pneumothorax was 5.24%. The number of punctures and patient's position and history of catheterization showed significant associations with pneumothorax development (p<0.001). Pneumothorax incidence in patients with score> 4 was 80% which was significantly higher than patients with score<4 (OR: 174.2, p<0.001). Sensitivity and specificity of using the scoring system at cut-off score> 2 were 81.8% and 87.9%, respectively. Conclusion: The results of this study showed that pneumothorax development risk is very low in patients with score<2 and there is no need for post CVC routine chest X-ray. However, in patients with score>4, pneumothorax development risk is high and it seems that chest radiography with close intervals even more than one time is necessary. Further studies are recommended to validate the proposed scoring system.

Abstract
Background: Catamenial recurrent pneumothorax is spontaneous pneumothorax in women of reproductive age, which includes 1-30% of spontaneous pneumothoraces in women and is associated with the menstrual cycle.
Case: A 39-year-old woman with sudden onset dyspnea, respiratory distress and decreased right side respiratory sounds with a history of spontaneous pneumothorax and chest tube placement one month ago. The patient's symptoms improved after chest tube placement and within less than 24 hours after onset, she began menstruating. Treatment was performed with chemical pleurodesis with tetracycline and oral danazol.
Conclusion: Catamenial pneumothorax and thoracic endometriosis should be considered in all women of childbearing age with spontaneous recurrent pneumothorax. Early detection of this syndrome can result in reduction of morbidity and mortality with recurrence episodes.
