The benign teratoma is usually slow growing tumor, but we expirienced a case of primary huge mediastinal benign teratoma that had grown very rapidly, maximally during 3 years. The 14-year-old female patient was admitted to our hospital because of abnormal chest X-ray that showed 10$\times$10cm sized well definded mass with multiple calcificactions. but the mass was not present in chest X-ray perfomed on 3 years prior to admission. Under the diagnosis of teratoma, complete surgical resection was done by the left thoracotomy. The result of pathology was benign teratoma.

We have experienced a case of primary thymic carcinoma. A 39 year old female patient admitted with incidentally detected mediastinal mass on chest film.The tumor showed invasion to surrounding tissues and the mediastinal lymphadenopathies were also noted. Invasion to contiguous mediastinal structures made complete surgical extirplation impossible and the biposy findings revealed primary thymic carcinoma. Primary thymic carcinoma is a rare neoplasm originating from the thymic epithelial cells. Clinical behavior of the thymic carcinoma is much different from it`s benign counterpart and several pathologic variants were reported.

Magnetic resonance imaging (MRI) has become a crucial tool for evaluating mediastinal masses considering that several lesions that appear indeterminate on computed tomography and radiography can be differentiated on MRI. Using a three-compartment model to localize the mass and employing a basic knowledge of MRI, radiologists can easily diagnose mediastinal masses. Here, we review the use of MRI in evaluating mediastinal masses and present the images of various mediastinal masses categorized using the International Thymic Malignancy Interest Group's three-compartment classification system. These masses include thymic hyperplasia, thymic cyst, pericardial cyst, thymoma, mediastinal hemangioma, lymphoma, mature teratoma, bronchogenic cyst, esophageal duplication cyst, mediastinal thyroid carcinoma originating from ectopic thyroid tissue, mediastinal liposarcoma, mediastinal pancreatic pseudocyst, neurogenic tumor, meningocele, and plasmacytoma.

A case of bronchogenic cyst associated with a partial pericardial defect is reported. Bronchogenic cysts are not so rare in incidence, but they are more rare when associated with a pericardial defect, the first case being reported by Rusby and Sellors in 1945. Recently, we experienced such a rare case of a bronchogenic cyst with a partial pericardial defect. The patient is a 39-year-old female and she was found to have a left anterior mediastinal mass during routine chest X-ray. During the operation, we detected partial pericardial defect after removal of the mediastinal mass. The pericardial defect was repaired with a Gore-Tex Membrane. The pathological examination of the mass showed a bronchogenic cyst. The patient had an uneventful hospital course.

Background: Neuroblastoma is the third most common malignancy of chidhood, and is the most common mediastinal mass in children under the age of 2 years. However, the results of surgical treatment have been seldomly reported in Korea. Therefore, we analyzed the results of surgical treatment in children with neuroblastoma and its influencing factors. Material and Method: We studied the clinical characteristics and prognosis of 12 children, 11 makes and 1 female, whose primary thoracic neurobalstomas or ganglioneuroblastomas were diagnosed and operated between 1977 and 1997. Men age at presentation was 29.9 months. Result: Respiratory symptoms were the modes of performed in 9 patients. Complete excision, partial excision, and biopsy only were performed in 9, 2, and 1 patients respectively. Ten patients of thoractic neuroblastomas survived (83.3%) during follow-up period. Conclusion: The postoperatve 5-year survival of thoracic neuroblastoma was 76.4% and the prognosis was related to the stage of neuroblastoma. We suggest that complete resection should be considered as preferential method in the treatment of thoracic neuroblastoma in children, especially with early stage.

The teratomas seem to be the most common mediastinal tumor in Korea. However, the immature teratomas are the rarest type of these mediastinal teratomas. A case of immature teratoma of the mediastinum occurring in a newborn male is reported. He suffered from severe dyspnea since birth. Simple chest X-ray and chest sonogram revealed huge mass shadow in fight whole lung field. On 6th day after birth, the operation was done and the mass was completely excised. Biopsy showed elements of mature tissues derived from 3 germ cell layers including immature neuronal components. The baby is well without evidence of disease till now.

Mediastinal paragangliomas are rare tumors that have only been reported in individual cases or limited case series. Surgical resection of these tumors can be challenging, as they are highly vascular and intimately related to the great vessels. Surgery is usually performed via median sternotomy with or without cardiopulmonary bypass. We present the case of a mediastinal paraganglioma that was resected via a left-sided posterolateral thoracotomy. Histopathology revealed a completely resected 38-mm paraganglioma with a positive station 5 lymph node, indicative of locally aggressive disease. Hereditary paragangliomas are associated with malignant transformation; therefore, genetic testing is important. These tumors do not respond well to chemoradiotherapy, and consequently lifelong surveillance for early detection of recurrence is recommended.

Dumbbell neurogenic tumor is a rare disease, arising about 10 % of mediastinal neurogenic tumor. We report a 31 year old man who was suffered from paresthesia and weakness of lower extremities for about 8 months. Chest x-rays revealed a dumbbell shaped mass shadow in left lower posterior mediastinum. MRI demonstrated a well defined dumbbell shaped mass in the mediastinum of T7 level, including spinal cord compression by the extended tumor into the spinal canal and enlarged intervertebral foramen. The patient underwent one-stage combined resection of the tumor through the thoracotomy and laminectomy, simultaneously. The tumor was confirmed as neurilemmoma. The postoperative course was smooth and uneventful.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is becoming a standard method for invasive mediastinal staging and for the diagnosis of paratracheal and peribronchial lesions. It is essential to understand the technical aspects of EBUS-TBNA to ensure safe and efficient procedures. In this review, we discuss the practical aspects to be considered during EBUS-TBNA, including anesthesia, manipulation of equipment, understanding mediastinal ultrasound images, target selection, number of aspirations needed per target, sample handling, and complications.

For the purpose of analysis of clinical and pathological characteristics in mediastinal tumors and cysts, 82 patients with mediastinal tumors and cysts treated in the department of thoracic and cardiovascular surgery in Chosun University Hospital during the period from January 1978 to December 1994 were reviewed. There were 49 male and 33 female patients in the study. Age ranges from 10 months to 84 years, with the mean 37.2 years. Frequently encountered symptoms and signs were dyspnea[40.2% , abnormal breathing sound[37.8% , chest pain[35.7% , cough[26.8% , and 18.2% of patients were asymptomatic. The most frequent tumor was anterosuperior mediastinum [59.8% followed by middle[24.4% and posterior mediastinum[15.8% . The malignant tumors were found in 35 cases[42.7% . Successful removal of the mass was possible in all the benign mediastinal masses[57.3% . But in the malignant cases, the surgical removal was possible in 18 cases and other inoperable cases were treated by radiation and chemotherapy. The postoperative complications occurred in 9 cases. Usual complications were bleeding[4 cases , wound infection[3 cases , pneumothorax[1 case and vocal cord paralysis[1 case . In the pathologic viewpoint, teratodermoid tumors[22.0% were the most frequent tumor followed by thymomas[19.5 , benign cysts[15.8% , lymphomas[13.4% and neurogenic tumors[8.5% .
