33-year old female was admitted chest surgery department for evaluation of mild chest pain. Chest plain film showed right anterior mediastinal mass and small metastatic daughter mass ipsilateral side. Exploratory thoracotomy was performed 24th Aug. 83 revealed that small nodular parenchymal mass at right middle lobe and large cystic mass at anterior mediastinum which was connected with anterior mediastinal fat. Histological examination confirmed diagnosis as pulmonary hamartoma and thymic cyst individually. We successfully treated these two masses by wedge resection and excision. Although postoperative course was uneventful, the cause and associated relationship between two tumor origin were obscure.

A 19-month-old boy suffered from stridor and dysphagia. He was taking asthma medication for a few months, but symptoms did not improve. After admission, a chest CT showed a posterior mediastinal mass, which compressed the trachea and esophagus. The removed mass via open thoracotomy was a bronchogenic cyst on histopathology. Postoperatively, stridor and dysphagia disappeared. In case of persistent and refractory stridor or dysphagia in children, congenital lesions including bronchogenic cyst need to be ruled out.

Pericardial cyst is an uncommon congenital mediastinal tumor. The majority of pericardial cysts are located in the right cardiophrenic angle, but rarely they can be located intrapericardially. We now present a case of a huge intra-pericardial pericardial cyst excised with video-assisted thoracoscopic surgery.

Bronchogenic cysts are rare congenital anomalies that arise early in gestation from abnormal budding of the developing respiratory system. Mediastinal bronchogenic cysts account for 10-15 percent of all primary mediastinal masses; 63.7 percent of patients are symptomatic. Common symptoms are fever, chest pain, cough, dyspnea, and dysphagia. Gastrointestinal symptoms except dysphagia are rare. It can be life threatening with compression, infection, hemorrhage, or rupture. Symptoms and signs of compression are more frequent in infants and children than in adults. It may be asymptomatic, or cough, infection, and hemoptysis may be observed. Complete excision is recommended. We report a case of bronchogenic cyst misdiagnosed as chronic gastritis with nausea and epigastric pain for a year.

This is a report on a total of 8 cases of benign mediastinal tumors and cysts in Department of Thoracic Surgery, Chonnam University Hospital during the period from 1961 to 1969. The patients age was distributed between 18 and 38 year old with the highest incidence in the age group of second decade. Sex ratio of male to female was 3: 5. The tumors were classificed as follow; 3 case:, of neurogenic tumors, 2 cases of teratomas, one case of pericardial cyst, one case of cystic hygroma, and one case of brochogenic cyst. The symptomatic patients were 5 cases(62. 6%) and asymptomatic patients were 3 cases(37.5%). The symptomatic patients had the symptoms not referable to their lesion and the mediastinal tumors of asymptomatic patients were incidently found by routine chest X-ray. The Symptoms occurred by compression to adjacent nerve system in 3 cases. by perforation into the lung with infection in one case and by infection of bronchial cyst in one case. The complications were Pancoast's syndrome including Horner's syndrome(2 cases), middle lobe syndrome (one case), bro:1chial infection(one case) and intercostal neuralgia(one case). All tbe tumors were surgicai[y resectable with good recovery postoperatively. In 5 cases of the symptomatic patents, their symptoms were disappeared dramatically after operation.

We report a very rare case of mediastinal tuberculosis in a 57-year old woman who presented with a large mediastinal cyst on chest radiography. She had a 10-year history of exertional dyspnea, but felt comfortable at a rest. A subsequent chest CT suggested a mediastinal cyst with mediastinal lymphadenopathy and communicating pericardial sac. She underwent a thoracotomy and excision of the mass, which was histologically revealed to be of tuberculous origin. Although rare, the apparent increase in the incidence of tuberculosis may result mediastinal cysts being diagnosed mediastinal tuberculosis. We also briefly review mediastinal lymphadenopathy due to tuberculosis.

A 67-year-old male patient came to the hospital due to lung cancer and mediastinal cystic mass which was suspected to be esophageal duplication cyst. Video-assisted thoracoscopic surgery (VATS) was performed and intra-operative finding suggested it as a cystic mass along the thoracic duct. Thoracic duct was ligated and the cyst was completely resected. A 48-year-old female patient visited the hospital for dysphagia. Mediastinal cystic mass was suspected to be an esophageal duplication cyst. Intraoperative finding suggest a thoracic duct lymphangioma. After thoracic duct ligation, the mass was completely resected with VATS. Postoperative chylothorax did not develop in both cases.

Thoracic duct cysts in the upper portion of the diaphragm are mostly found in the neck and are rarely found in the mediastinum. Thoracic duct cysts should be differentiated from other mediastinal tumors or cysts, and surgical treatment is required to avoid the development of chylothorax if the cyst ruptures. Herein, we report the case of a patient with a thoracic cyst located just above the diaphragm that was treated with surgical resection.

This report is a review of 98 cases of the primary mediastinal tumors which are treated in the Department of Thoracic and Cardiovascular Surgery, Chonnam University Hospital from January, 1985 to February, 1993 and divided two groups. One group is from January, 1985 to January, 1989 and named it Group 1[G1]. Another group is from February, 1989 to February, 1993 and named it Group 2[G2]. Chest pain is the most common clinical manifestation in the two groups. The common mediastinal tumors are teratoma 11 cases[29.7%], neurogenic tumor 7 cases[18.9%], thymoma 6 cases[16.2%], primary cyst 3 cases[8.1%] in Group 1 and thymoma 16 cases[26.2%], teratoma 15 cases[24.6%], neurogenic tumor 9 cases[14.8%], primary cyst 9 cases[14.8%] in Group 2. Therefore this result shows that the incidence of thymoma is increased in group 2. In benign tumors, the subjective symptoms are 64.3% in group 1 and 63.6% in group 2. In malignant tumors, they are 100% in group 1 and 82.4% in group 2. this result shows that asymptomatic malignant tumors are increased in group 2. The successful excision is done in all of the 71 benign tumors except one. In malignant tumors, the complete surgical excision is increased from 11.1% in group 1 to 41.2% in group 2.

We have experienced two cases of video thoracosopic excision of mediastinal tumors at the department of thoracic and cardiovascular surgery, Yonsei University, College of medicine. Histologically the mediastinal tumors were cystic thymoma in one & bronchogenic cyst in another. The operative times were rather short and the post-operative courses were not eventful. These patients were discharged with less chest discomforts in post-operative 5 days & have been in good conditions to now.
