Two cases of benign mediastinal tumor were treated by complete resection under the video-thoracoscopic guidance. The procedure has been performed on the 2 patients, allowing definite treatment and was less invasive than standard surgical treatment. The 2 patients have been benefited by decreased postoperative pain, reduced scarring of the skin and rapid recovery. Two patients had benign mediastinal tumors; teratodermoid on anterior mediastinum and neurilemmoma on posterior mediastinum. There were no operative death and complication, median hospital stay was four days.

A 42-year old male was seen with symptoms of dysphagia, chest pain and dyspnea of 9 months duration. A benign tumor of the posterior mediastinum was diagnosed from x-ray studies and a transthoracic needle aspiration biopsy which was inconclusive. A left thoracotomy revealed a huge mass occupying the retrocardiac space and the contra-lateral mediastinum. It was resected by blunt dissection and, during this process, a 3.0 cm laceration was created in the esophageal wall. This was repaired with Tevdec sutures and staplers and was reinforced with an intercostal muscle flap to prevent leakage. The postoperative course was entirely uneventful.

A 45 year old man was admitted for further examination of an abnormal shadow of the right posterior mediastinum. The patient suffered from dysesthesia in the right thoracic wall of dermatome T7. CT scan and MRI revealed that two separate tumors had developed in the right paravertebral area linked to the vertebral canal via an intervertebral foramina. One-stage removal of the tumors were performed safely through the right posterolateral thoracotomy following the resection of the rib head and vertebral pedicle. The tumors were confirmed as histologically neurilemomas. The postoperative course was uneventful.

We report three cases of posterior mediastinal tumor in Von Recklinghausen's disease on 12-yearsy old boy, 8-years-old girl and 6-years-old boy. Especially the last case was combinded with "Dumbbell" neurilemmoma of cervical spine. In the first case, preoperative CT scan showed a homogeneous large mass In the posterior mediastinum. But the mass did not show intraspinal invasion on the chest MRI scan. In the last case, cervical spine CT with thecal enhancement shows dumbbell shaped neurofibroma, compressed spinal cord and thecal sac In three cases we removed all the masses successfully and the patients were discharged safely without significant problem.t problem.

A 71-year-old male patient visited Yeungnam University Hospital with abnormal chest computed tomography (CT) findings. Chest CT revealed multiple lung nodules and a posterior mediastinal tumor, the diagnosis of which was confirmed surgically. Magnetic resonance imaging (MRI) of the abdomen showed multiple small nodules, which were diagnosed as cavernous hemangioma in the liver based on the pathology results of the mediastinal and lung masses in combination with MRI findings. Cavernous hemangiomas are benign tumors that can occur throughout the body, mainly in the skin and subcutaneous tissue. The liver is the most common internal organ containing hemangiomas, whereas they are very rarely found in the lungs or mediastinum.

A 21-year-old male was admitted for evaluation of a mass shadow on chest film. On chest computed tomography showed 5 cm sized homogeneous low density based on the second thoracic vertebral body in the posterior mediastinum. The patient had been performed thoracic sympathectomy 6 months before admission and oxidized cellulose was used for hemostasis at that operation. Surgical resection was performed and microscopic result was foreign body granuloma caused by oxidized cellulose. Oxidized cellulose is an absorbable sterile mesh and used to control capillary or venous bleeding. Although the manufacturer recommends its removal after hemostasis is achieved, in clinical practice it is usually left in situ to reabsorb spontaneously, usually with no untoward effect.

Mesothelial cyst is a rare mediastinal tumor and usually presents in the right cardiophrenic angle. However, it sometimes occurs in atypical locations and it’s locating in the posterior mediastinum, especially, is very rare. A large cystic mass of the posterior mediastinum between pericardium and vertebral body was incidentally recognized in a patient of a 30-year-old woman admitted due to traffic accident. Even though it was very large in size measuring 18 em at longest diameter and is extending mainly to the left pleural cavity, she had no symptomatic complaints. Complete excision was performed through video-assisted thoracoscopic surgery with a additional small working window, which was necessary for dissecting the deepest point to the right pleural cavity. She is in good condition without recurrence on long-term follow-up.

We have experienced 50 cases of mediastinal tumors and cysts from March, 1979 to August, 1985 at Kyung Hee University Hospital. The results of this cases analysis were as followings; 1. Of all 50 mediastinal tumors and cysts, 26 patients were male and 24 patients were female. There was no sex preference. The age distribution was from 27 months to 64 years, and mean age was 33.5 years old, and also no age preference. 2. The most common mediastinal tumor was benign cysts [12 cases], which comprise 24% of all mediastinal tumors and cysts. The second common mediastinal tumor was teratoma [9 cases-18%], and followed by thymic tumors and tuberculous granuloma [7 cases-14% each], neurogenic tumors [5 cases-10%], and other tumors [10 cases-20%]. 3. The anterior mediastinum was most common tumor location, and followed by middle, superior, and posterior. 4. All 9 teratomas were developed at anterior mediastinum, and 4 of 5 neurogenic tumors were developed at posterior mediastinum. Thymomas were developed at anterior and superior mediastinum. The bronchogenic cysts had no predilection of location. 5. The most common chief complaint at admission was chest pain or discomfort [23 cases-46%], and followed by cough with or without sputum, and exertional dyspnea. Asymptomatic patients were only 7 patients [24%]. 6. Of all 50 cases, 38 cases [76%] received radical tumor resection, 7 mediastinoscopic biopsy, 3 explo thoracotomy and biopsy, and 1 neck mass biopsy. 7. There were 2 hospital deaths, one of which was a patient who suffered malignant thymoma and Myasthenia Gravis. The patient received radical tumor excision, but died at 7th POD. The other patient was a patient with malignant transformation of the benign cystic teratoma. The operative mortality was 4%.

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.

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.
