The mediastinum consists of superior and inferior components.
++
The superior mediastinum is a self-contained region that transmits structures between the neck, upper limb, and the inferior mediastinum. It is a complex region that contains representatives of every type of structure in the body. Expanding pathology here can easily cause compression of the contents.
++
The inferior mediastinum is divided into anterior, middle, and posterior mediastina.
++
The anterior mediastinum is not often involved in significant pathology.
++
The middle mediastinum contains the pericardial cavity (with its contents) and the area between the lung hila.
++
The posterior mediastinum transmits structures between the superior mediastinum and the abdomen.
++
Normal imaging of the chest may be viewed in ‘pleural cavity.’
