Chest wall chondrosarcomas are a rare cause for an anterior mediastinal mass. Commonly patients present with a painless palpable mass with a third of patients describing diffuse chest pain. We present a patient with an anterior mediastinal chest wall chondrosarcoma presenting with neurological symptoms and flushing. As more of these cases are seen and reported this rare entity is more likely to...

Mediastinal fibrosis is a rare, benign disorder characterised by proliferation of fibrous tissue within the mediastinum. It can present as diffuse mediastinal infiltration or, more frequently, as a localised soft tissue mass, usually in the right paratracheal or subcarinal areas. 18-fluorodeoxyglucose (18-FDG) positron emission tomography (PET) imaging has only been reported in a few case repor...

Liposarcoma occurs very rarely in the mediastinum. Patients often remain asymptomatic until it grows large enough to cause direct invasion or compression of adjacent organs. We report a case of a 77-year-old male presented with dyspnea of exertion and was found to have a large mediastinal mass which was eventually diagnosed as primary mediastinal well-differentiated liposarcoma. The limited res...

There is no existing worldwide published method for mediastinum compartment classification based on transverse section images for the differential diagnosis of mediastinal tumors. Herein, we describe a new method for anatomic mediastinal compartment classification using transverse section computed tomography (CT) images and the use of this method to classify mediastinal lesions, and thus evalua...

A 67-year-old male patient came to the hospital due to lung cancer and mediastinal cystic mass which was suspected to be esophageal duplication cyst. Video-assisted thoracoscopic surgery (VATS) was performed and intra-operative finding suggested it as a cystic mass along the thoracic duct. Thoracic duct was ligated and the cyst was completely resected. A 48-year-old female patient visited the h...

Paragangliomas are unusual neuroendocrine cell tumors arising from paraganglia, of which ACTH-secreting cases in the mediastinum are extremely rare. A 51-year-old woman was admitted for generalized edema and weakness which began 5 months ago. Chest X-ray and CT scan revealed a tumor mass in the anterior mediastinum. The plasma cortisol and ACTH levels were very high. Other sources secreting ACT...

Primary mediastinal sarcomas are aggressive tumors with a very rare incidence. This report describes the case of a 35-year-old male patient who presented with acute symptoms of dyspnoea, facial puffiness, voice-hoarseness, and engorged neck veins. With the clinical picture consistent with the superior vena cava (SVC) syndrome, the patient was investigated with computed tomography of the chest. ...

Venous aneurysm of the azygos arch is a very rare cause of mediastinal mass and is usually an incidental finding on chest radiography. Nowadays the diagnosis is made by non-invasive tests such as thoracic CT scanning and/or magnetic resonance imaging. The case is described of an asymptomatic woman in whom a mediastinal mass due to an azygos vein aneurysm was diagnosed by non-invasive procedures...

Single-port thymectomy (SPT) with a subxiphoid approach is indicated for anterior mediastinal tumors and myasthenia gravis when preoperative diagnostic imaging reveals no tumor infiltration into the surrounding tissues, such as the brachiocephalic vein and pericardium. The present case is a 42-year-old female patient who had an incidental finding of an anterior mediastinal cystic mass during fo...
