OBJECTIVE To determine if the 8 cm upper limit for mediastinal width applies in the trauma setting of today. To define the upper limit of normal mediastinal width for supine chest films. METHODS A retrospective review of chest computed tomography scans was conducted to determine the width and position of the mediastinum within the supine chest. Radiographs were performed using a model that en...

Liposarcomata most frequently originate in the interfascial plane of the thigh, or in the retroperitoneal tissues.' Primary development in the mediastinum is a rare occurrence, with less than 60 cases reported in the world literature.2 3 4 5 Histopathologically, liposarcomata are classified into four basic types: well differ entiated, myxoid, round cell and pleomorphic, and the clinical behavio...

Leiomyoma of the mediastinum is rare. We report a case of a 57-year-old woman with a cervical mass diving to the intrathoracic. Chest radiography and computed tomography revealed a mass in the right superior mediastinum. The tumor was enucleated by cervicotomy. Histologically, the tumor was diagnosed as leiomyoma.

Mediastinoscopy is a safe and simple endoscopic procedure for the exploration of the superior mediastinum. It provides useful information as to the possible resectability of bronchogenic carcinoma, or for establishing the diagnosis of primary tumors of the mediastinum, metastatic disease and a variety of chronic granulomata.

Cavernous hemangiomas of the anterior mediastinum is rare. We present a case of a 56-year-old male patient with a giant cavernous hemangioma of the anterior mediastinum, 18 cm in diameters, approached by left posterolateral thoracotomy. To the best of our knowledge, such a unique case has not been previously presented in the literature.

Bronchogenic cyst is a common primary of the mediastinum, and it usually located in middle mediastinum intrapulmonary regions. cysts are lesions congenital origin that occur due to abnormal budding from primitive ventral foregut. They pediatric age group have symptoms respiratory distress, recurrent cough, wheezing, stridor. Definitive management involves surgical excision. We herein report our...

Patient. A 62-year-old man presented with effort dyspnea, non-productive cough and weakness of 4 month duration. He had no findings on physical examination.Discussion. Chest X-ray revealed a large mass in the left anterior mediastinum. Computerized tomography of the chest showed a well-delineated homogeneous mediastinal mass with fat-equivalent density and a small pleural effusion. Fiberoptic b...

Teaching Point: Lipoblastoma should be considered in the differential diagnosis of painful rapidly growing fatty mass within mediastinum infants or young children under three years old.

A perivascular epithelioid cell neoplasm (PEComa) in the chest is rare, let alone in the mediastinum and lung. A 63-year-old man was admitted to our hospital with chest pain for more than 2 months and was found to have an opacity in his mediastinum and lung for 3 weeks. Enhanced chest computed tomography (CT) revealed a mass in both the left upper lobe and central anterior mediastinum. To ident...
