Bronchogenic cysts are congenital malformations of the bronchial tree, a type of bronchopulmonary foregut malformation. The presentation of the bronchogenic cyst is variable, making pre-operative diagnosis difficult. They aremostly asymptomatic orarefound incidentally when the chest is imaged. They can present as lower neck massesor mediastinal masses that may enlarge. They cause mass effect due to local compression and may result in tracheo-bronchial obstruction leading to air trapping and respiratory distress. The treatment is somewhat controversial, and in general,these lesions are treated using the transcervical or transbronchial approach. When these cysts arelocalized in the upper mediastinum, it may be possible to removethemusing the transcervical approach. In our three cases, the patientscomplained of mild dysphagia, foreign body sensation, and dyspnea. We report three cases of a large bronchogenic cyst in the lower neck and the upper mediastinum treated using the transcervical approach.

Bronchogenic cysts are uncommon congenital anomalies and commonly located in the mediastinum or lung parenchyma. Bronchogenic cyst in cervical area is rare and in posterior pharyngeal area is exteremely rare. Clinically, it is usually asymptomatic and incidentally diagnosed. It is pathologically confirmed only when there are bronchial tissues such as pseudostratified ciliated columnar epithelium, smooth muscle cells, mucous gland and/or cartilage. Since it has potential for malignant transformation and complication, complete excision is essential. We report a case of bronchogenic cyst located in the retropharyngeal space with a review of literature.

Bronchogenic cysts are rare congenital anomalies of the tracheobronchial tree. Most cases present within the mediastinum or pulmonary parenchyma without a patent connection to the tracheobronchial tree or digestive tract in the pediatric age group. Cervical bronchogenic cysts in adults are rare. In this report, we describe two cases of incidentally found paratracheal bronchogenic cysts that presented as asymptomatic neck masses in a 66-year-old female with papillary thyroid carcinoma and in a 59-year-old male of Catleman's disease.

A bronchogenic cyst is an uncommon benign congenital anomaly of the primitive ventral forgut which was generally encountered within the mediastinum and detected in pediatric patients. It is rarely detected in adult population as a lateral neck mass. We have recently experienced one case of bronchogenic cyst as a left lateral neck mass in a 49-year-old male. He complaints of a $2{\times}1$ cm sized, soft, non tender, and movable mass on the low lateral neck. The surgical excision of mass was performed and the final histopathologic diagnosis was a bronchogenic cyst. Here, we report this case with the review of literatures.

Due to its less invasive nature and superior visual field, video-assisted thoracescopic excision of mediastinal mass is thought to be comparable to open thoracotomy. Material and Method : From January 1995 to August 2001, the medical records of 38 patients who underwent video-assisted thoracoscopic excision of mediastinal mass was retrospectively analyzed. The outcome of these patients were compared with 5 patients who converted to thoracotomy Result: Male to female ratio was 13(34.2%) : 25(65.8%), and mean age was 39.2$\pm$35.4 years. Regarding the pathology, there were 8 neurilemmomas(21.1%), 6 thymic cysts (15.8%), 5 teratomas(13.2%), 5 ganglioneuromas(13.2%), 4 bronchogenic cysts(10.5%), 3 pericardial cysts(7.9%), 3 thymomas(7.9%), and 2 lymphangiomas(5.3%). The mean operation time was 110.6$\pm$7.0 minutes, mean postoperative tube stay was 4.2$\pm$0.4 days, mean postoperative hospital stay was 5.2$\pm$0.4 days, and mean number of injection of analgesics was 1.9$\pm$0.4 times. Although the mean values for the above indices were less than those of the thoracotomy conversion cases, they were statistically insignificant. Postoperative complications of videoassisted thoracoscopic excision included chylothorax, prolonged air leakage, and unilateral phrenic nerve palsy, all of which recovered before patient discharge. There was, however, permanent unilateral ptosis in one patient. Conclusion : As video-assisted thoracoscopic excision of mediastinal mass is safe, less painful, conducive to earlier recovery and cosmetically more appealing, a more active application of this technique is recommeded.

Recently, video-assisted thoracoscopic surgery for mediastinal lesions has been considered a new effective therapeutic method. From March, 1992 to April, 1997, 33 cases of video assisted thoracoscopic surgery for mediastinal lesions were performed. Gender distribution was 16 males and 17 females. Average age was 42 years old(ranged from 14 to 69). The locations of lesions were anterior mediastinum in 14 cases, middle mediastinum in 5 cases, posterior mediastinum in 11 cases, and superior mediastinum in 3 cases. These included 9 neurilemmomas, 5 benign cystic teratoma, 4 pericardial cysts, 2 ganglioneuroma, 2 thymus, 2 thymic cyst, 1 thymoma, 2 esophageal leiomyomas, 1 dermoid cyst, 1 lipoma, 1 malignant lymphoma, 1 bronchogenic cyst, 1 pericardial effusion, and 1 Boerhaave's disease with empyema. Working window was needed in 6 cases. We converted to open thoracotomy in 6 cases. Reasons of convertion to open thoracotomy were large sized mass(1), severe adhesion(3), and difficult location to approach(2). The average operation time was 116min($\pm$56 min). The average chest tube drainage time was 4.7days. The average hospital stay was 8.7 days. Operative complications were atelectasis(2), empyema with mediastinitis(1), recurrent laryngeal nerve palsy(1), and plenic nerve palsy(1). In conclusion, VATS for mediastinal lesions were performed with shorter operation time and hospital stay, and lesser complications and pain than those of conventional thoracotomy.
