ABSTRACT
Hemangiomas of mediastinum are rare lesions comprising less than 0.5% of all mediastinal masses. Posterior mediastinal hemangiomas are less common than anterior mediastinal. A 21 year old female was refered to our hospital because of abnormal mediastinal shadow in simple chest X-ray. Chest CT scan and T-spine MRI revealed a posterior mediastinal dumbbell-shaped mass with extradural extension. Surgical excision was performed and pathologic diagnosis was confirmed as 3x4x2 cm sized capillary hemangioma.

Neurogenic tumors are common in posterior mediastinal tumors. In most cases, tumors were accidentally showed on simple chest X-ray. In some cases, they were presented by symptoms which were induced by nerve compression or airway compression. But as in our case, neurogenic tumor with spontaneous hemothorax is very rare. A 45-year-old man admitted to emergency room of other hospital because of acute right chest pain and dyspnea. A chest X-ray showed a right pleural effusion. Hemothorax was diagnosed after closed thoracostomy. Following chest CT showed posterior mediastinal mass. The patient was transferred to our hospital. T spine MRI showed dumbbell shaped mass. Diagostic impression was neurogenic tumor. The pathologic result was neurilemmoma after surgical resection.

Development of intraoperative aortic dissection during coronary artery bypass surgery is extremely rare with catastrophic outcomes resulting in high rates of morbidity and mortality. The prognosis is highly dependant upon prompt diagnosis and emergent treatment. We report our experience on a 72 year old female patient who successfully received ascending aortic graft replacement for acute intraoperative aortic dissection during coronary artery bypass procedure.

Chest wall metastases from malignant tumors are rare and the majority of them are from adjacent structures such as the breast, lung, pleura, and mediastinum. Paticularly, chest wall metastases from distant organs are an even rarer event. There are few reports of chest wall metastasis with obscure or absent primary tumor. A 51-year-old man was diagnosed with metastatic hepatocellular carcinoma after an operation for a palpable mass on his left upper chest wall. At that time, there was no evidence of primary hepatocellular carcinoma in the liver after various examinations. We report a case of chest wall metastasis from unknown primary hepatocellular carcinoma.
