A mediastinal tumor is a tumor in the mediastinum, the cavity that separates the lungs from the rest of the chest. It contains the heart , esophagus , trachea , thymus , and aorta . The most common mediastinal masses are thymoma (20% of mediastinal tumors), usually found in the anterior mediastinum, followed by neurogenic Timor (15–20% ...

Above the hilum of the lung is an arched groove for the azygos vein , and above this is a wide groove for the superior vena cava and right brachiocephalic vein ; behind this, and close to the top ...

In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest, called the mediastinum. [4] In humans, the heart is divided into four chambers: upper left and right atria and lower left and right ventricles.
The mediastinal branches are numerous small vessels which supply the lymph glands and loose areolar tissue in the posterior mediastinum. References
The mediastinal pleura is the portion covering the lateral surfaces of the mediastinum, predominantly the fibrous pericardium, the thoracic aorta, the first part of the subclavian artery, the superior vena cava/azygos vein, the esophagus and (very rarely) an enlarged thymus.
