The International Thymic Malignancy Interest Group ITMIG classification of mediastinal compartments was developed to reflect a division of the mediastinum based on cross-sectional imaging. It was in part an effort to consolidate prior discrepant classification systems in use by different medical specialties. A working group composed of approximately experts in thoracic surgery, medical oncology, diagnostic radiology, and pathology were tasked with forming a practical system for anatomic classification which unified the various systems. The ITMIG classification divides the mediastinum into three compartments: prevascular, visceral and paravertebral 1,2.

The mediastinum is a space in the thorax that contains a group of organs, vessels, nerves, lymphatics and their surrounding connective tissue. It lies in the midline of the chest between the pleura of each lung and extends from the sternum to the vertebral column. Division of the mediastinum is generally conceptualized as comprising 3 or 4 compartments, depending on the schema.
For example, the mediastinum can be divided into parts based on their relationship to the fibrous pericardium :. Historically, there has been discrepant definitions of the mediastinal compartments between medical disciplines. For example, radiologists originally used arbitrary radiologic landmarks on lateral radiographs, while surgeons considered the mediastinum according to anatomic limits encountered intraoperatively e.
Shields classification. In response, there have been efforts to reconcile mediastinal classification systems for consistency. Broadly, pathology that affects the mediastinum can be divided into those that result in a focal mass, or those that result in diffuse disease involving the mediastinum.
The differential diagnosis of a mediastinal mass is highly dependent on its location within the mediastinum, as this may reveal the structure of origin. Thus, there is a specific differential diagnosis for each compartment:.
In cases where localization is difficult due involvement of multiple compartments, the ITMIG recommends a "center method" technique by which the central point on the axial slice where the lesion appears largest is used for localization. Finally, air tracking into the potential mediastinal spaces pneumomediastinum may occur when there is rupture of an air-containing structure, penetrating injury, or may be iatrogenic.

The mediastinal lines visible at conventional radiography represent the interfaces between the mediastinum and adjacent lung parenchyma. Preservation, obliteration, thickening and distortion of these lines represent the key to detecting and localising mediastinal abnormalities on chest radiographs.
