hydatid disease, caused by echinococcus granulosus, is a common infectious disease in endemic areas such as southern europe and the middle east. the incidence of this disease, however, is on the increase in northern europe due to the migration of labor and also tourism. we report a case of the hydatid cyst of the mediastinum, the diagnosis of which was established by the hemagglutinin test and ...

difficult to treat asthma is an asthma syndrome that brings in our mind other differentials. mediastinal masses are not common findings, but are important variables. bronchogenic cyst is a congenital anomaly of the foregut that is typically found in the mediastinum and diagnosed accidentally. we present a 4-year-old girl with allergic asthma that began at 8-months of age and finally a bronchoge...

ectopic thyroid tissue (ett) is a rare entity and a challenging differential diagnosis. this is a report of a case of a mediastinal mass that was found to be an ectopic mediastinal thyroid tissue, in a 77-year-old woman who was admitted to our hospital for breast cancer management. the mediastinal mass was identified in the postsurgical computed tomography (ct) scan of the chest and was suspect...

a middle-aged woman with the chief complaints of dysnea and chest pain was referred to our center. chest x-rays and computed tomoram revealed a mass in the posteriof mediastinum, which was excised in toto. pathologicat report of the specimen labeled it as normal thyroid tissue (aberrant thyroid).

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...

malignant peripheral nerve sheath tumor (mpnst) is a rare nerve sheath tumor derived from schwann cells or pleuripotent cells of neural crest. neurogenic tumors make about 10-20% of all mediastinal tumors. incidence of mpnst is 0.001% in general population and 0.16% in patients with neurofibromatosis i (nf i). we report a case of 60 year female presenting with progressive cough and breathlessne...

1. Rupture of marginal alveoli into the pulmonary interstitial tissue and thence to the mediastinum 2. Mixed aetiological factors (The mode of production is not yet certain.) (a) Spontaneous pneumomediastinum (b) Trauma to the chest wall 3. Air entering the mediastinum from the deep fascial planes of the neck 4. Air entering the mediastinum from the retroperitoneal space 5. Perforation of the t...

Mediastinal masses can be benign cysts, neurogenic tumors, germ cell neoplasms, thymomas or lymphomas. The mediastinum is demarcated by the pleural cavities laterally. Superior to the mediastinum, you find the thoracic inlet. The mediastinum is usually divided into three main compartments, anterior, middle and posterior. This anatomical classification of the mediastinum is useful for the radiol...
