Widened mediastinum

Widened mediastinum/mediastinal widening is a mediastinum with a measured width greater than 6 cm on an upright PA chest X-ray or 8 cm on supine AP chest film.^{[citation needed]}

Associated conditions

A widened mediastinum can be indicative of several pathologies:^[1]^[2]

aortic aneurysm^[3]
aortic dissection^[4]
aortic unfolding
aortic rupture
hilar lymphadenopathy
anthrax inhalation - a widened mediastinum was found in 7 of the first 10 victims infected by anthrax (Bacillus anthracis) in 2001.^[5]
esophageal rupture - presents usually with pneumomediastinum and pleural effusion. It is diagnosed with water-soluble swallowed contrast.
mediastinal mass
mediastinitis
cardiac tamponade^[6]
pericardial effusion
thoracic vertebrae fractures in trauma patients.
