Neurogenic tumors of the mediastinum may have an intraspinal component connected by a narrowed segment of tumor in the intervertebral foramen, then have symptoms of back pain,lower extremity tingling sensation. CT scan or MRI demonstrated a Dumbbell-shaped mass density compressing spinal canal, enlargement of the foramen, erosion of bone, and intervertebral widening. We report the analysis of the 18 cases of neurogenic tumors on posterior mediastinum and Dumbbell type tumors are 3 cases among the 18 cases. The neurilemmomas were 12 cases[67%], the ganglioneuroma were 5 cases[28%], and neuroblastoma was one case[5%]. The successful removal was done in all cases, a standard thoracotomy and laminectomy was done in Dumbbell type tumors.There was no postoperative neurological complications.

Hemangiopericytoma is a rare tumor of vascular origin, first described by Stout and Murray in 1942. It is characterized by a proliferation of capillaries, surrounding by a mass of spindle shaped or round cells. A 55 year-old man was admitted with a 2 years history of dull pain on the right upper posterior chest and mild dyspnea on Feb. 1978. On admission, chest PA and right lateral x-ray showed a large well defined homogenous increased density in the right upper posterior chest. Yellowish to brownish colored huge firm mass, which occupied entirely the right superior posterior mediastinum, was removed. The tumor was dense adhesive with right upper & lower lobe and Rt. upper posterior chest wall. The origin of tumor was not obvious. The tumor was confirmed as hemangiopericytoma, locating at the right posterior mediastinum by histopathologic examination. The postoperative course was uneventful, and he was made irradiation therapy after discharge.

The malignant germ cell tumor found in the gonad can originate in the anterior mediastinum. Endodermal sinus tumor[Yolk sac tumor] is a kind of malignant germ cell tumor and is derived from extra-embryonic mesoderm. We experienced a case of primary mediastinal endodermal sinus tumor occurred in 22 year old male patient. His chief complaint was anterior chest pain for 2 days. The tumor located in the anterior mediastinum and invaded upper lobe of the deft lung and pericardium. A left upper lobe resection including phrenic nerve and pericardium was performed and the tumor in the anterior mediastinum was excised. The patient has been treated with combination chemotherapy[Cis-platinum, Vincristine, Actinomycin-D, & Cyclophosphamide} and followed up for 4 months with partial remission.

A 36-year-old man visited Yeungnam University Hospital with a sudden onset of palpitation, headache, and was found to be hypertensive. Chest radiography showed a 6 cm sized mass lesion on the posterior mediastinum. A biochemical study showed elevated levels of catecholamines. An I-123 metaiodobenzylguanidine scan revealed a hot uptake lesion on the posterior mediastinum. The patient was prepared for surgery with ${\alpha}$ and ${\beta}$ blocking agents. Two months later, we removed the tumor successfully. A histological study proved that the resected tumor was mediastinal pheochromocytoma. Functional mediastinal pheochromocytomas are rare. Therefore, we reported the case with a literature review.

Giant lymph node hyperplasia (Castleman's disease) is a nonneoplastic lymphoproliferative disorder of unknown etiology that usually occurs in the chest. Its morphological recognition is based on a composition of various histological features. The mass is often asymptomatic, but it can cause nonspecific thoracic symptoms, such as regional pain. This disease can be found wherever lymph nodes are present, but two-thirds of these tumors are found in the chest, along the tracheobronchial tree in the mediastinum or lung hilus. However, we experienced an unusual case of Castleman's disease as a cause of back pain that was localized in the posterior mediastinum bordering the chest wall.

The lipomatous of the mediastinum are fairly uncommon tumors. Since 1971, two patients with proven mediastinal lipoma and one primary liposarcoma of the mediastinum have been treated at the Seoul National University Hospital. This report reviews our experience with the review of literature. Case 1.: A 3 year old body revealed a huge round homogenous mass density in the posterior mediastinum in routine chest X-ray. The tumor mass, lipoma, was successfully removed and postoperative course was uneventful. Cases 2.: An asymptomatic 24 year old male was operated on with the preoperative diagnosis of mediastinal lipoma. His preoperative chest X-ray and CT films showed a huge anterior to middle mediastinal tumor, right, with fat density. There is no postoperative problem after successful removal of the tumor mass. Case 3. : A 24 year old female was hospitalized with the complaints of cough and chest pain. A mediastinal mass was removed, which proved to be a liposarcoma on pathologic examination. About one year later, she was found to have recurrent liposarcoma in the right chest area at the OPD follow-up. She was lost to follow-up since then.

Bronchogenic cysts are a congenital cystic lesion which are usually found within the lung parenchyme or mediastinum. Two cases of bronchogenic cysts were presented and related literatures were reviewed. The first case of bronchogenic cyst was located in the wall of the esophagus. Preoperatively, this case was thought duplication cyst of esophagus, but postoperative microscopic examination showed the tumor was a bronchogenic cyst with respiratory epithelium. The second case had double cysts; one in the superior and posterior mediastinum, the other in the lung parenchyme. The cyst in the mediastinum was extirpated and the other cyst in the lung was removed by right upper lobectomy. Postoperative course were uneventful in both patients.

Intrathoracic cyst was considered rare entity but one of the important diseases in the field of thoracic surgery. Authors had experienced 17 cases of intrathoracic cysts that were treated in the department of thoracic and cardiovascular surgery of Pusan NationalUniversity Hospital for 10years from January, 1983. to December,1992. The summary is as follows: Their age distribution was from 2 years and 9 months to 59 years of age, mean age 27.2 years. There were 8 males and 9 females. The type of intrathoracic cyst was 10 cases of Bronchogenic cyst, 2 cases of Pericardial cyst and 4 cases of Non specific cyst. The anatomical locations of intrathoracic cysts were 6 cases of anterior mediastinum, 2 cases of middle mediastinum, 3 cases of posterior mediastinum and 6 cases of lung parenchyme. The most common symptom was coughing and followed by general weakness, fatigue, chest pain & discomfort and hemoptysis and 6 patients were asyptomatic. The successful complete removal was done at all cases.Postoperative complications were developed in 5 patients but there was no case of hospital mortality.

A retrospective analysis was performed on 36 patients with primary cysts and tumors of the mediastinum seen at the Department of Thoracic and Cardiovascular Surgery of Maryknoll Hospital from January 1983 to December 1993. There were 21 female and 15 male patients in the study. Ages ranges from 2 years to 72 years, with a mean of 34.7. There were 9 malignant tumors and 27 benign tumors.Thymic neoplasms were the most common. For the whole series, 29 of the patients had tumors in the anterior mediastinum. There appears to be an in6rease in tumors in the anterior compartment. There were 30 symptomatic patients in our series. Of the patients with malignant disease, 89 % were symptomatic. All of benign tumors were completely removed and malignant tumors were treated with chemotherapy and radiotherapy after operation. There were 9[27.3 %] postoperative complications. There was no postoperative mortality. Follow-up was available on 27 patients. There was no recurrence, malignant degeneration, or growth of any tumor. It is hoped that careful evaluation and aggressive treatment of mediastinal tumors will continue to provide improvement in the prognosis for these patients.

Lymphangiohemangiomas of the mediastinum are exceedingly rare and few cases have been published in the English literature. This report may be the only reported case in which lymphangiohemangiomas were found bilaterally. We report a case of a 7-year-old boy with an incidental finding of an abnormal mediastinal shadow on a chest X-ray. The chest CT showed a large mass in the left superior mediastinum and another in the right posterior mediastinum. The left mass had anomalous venous channels connected to the left innominate vein, and the right mass to the left atrium. We performed an excision of the mass in the left side first and then the right side one month later. Anomalous venous channels were dissected carefully and ligated. There were no complications and no signs of recurrence 30 months after the operation.
