Establish the diagnostic
WIDENED mediastinal shadow (esp. in the superior region)
CAN BE:
REGULAR: MEDIASTINITIS (fine layers)
IRREGULAR: TUMORS (usually polycyclic)
In some particular situations:
Expanded tumor related to the aorta: AORTIC ANEURYSM
Polycyclic shadows: LYMPHADENOPATHIES
TUMOR, ATELECTASIA: PULMONARY CANCER
