Multiple Pulmonary secondaries

The mediastinal shadow is dominated by the dilation of the aorta. Better definition of the aortic anatomy is achieved with the CT scan during which iodinated contrast material is injected to opacify the blood pool in the dilated aorta

Pulmonary T. B. Thoracic aortic aneurysm

Rt. side tension pnemothorax

Lt. side tension pnemothorax

Massive Rt. pleural effusion

Lt. lung collapse Lt. lung pneumonia Rt. lung effusion Causes of an Opacified Hemithorax Lt. neumonectomy

Lt. lung collapse There is a shift of heart and hemidiaphragm toward side of opacification (toward side of volume loss)

The right hemithorax is opaque There is a shift of the heart and trachea toward the side of the opacification Atelectasis of the Right Lung

Rt. lung effusion If an effusion (whatever the fluid is) fills the entire hemithorax It acts like a mass Pushing the heart and trachea away from the side of opacification

The right hemithorax is opaque There is a shift of the heart and trachea away from the side of opacification Large Right Pleural Effusion

Lt. lung pneumonia The hemithorax is opaque and there is no shift of the heart or trachea

The left hemithorax is opaque There is no shift of the heart or trachea The opacified hemithorax contains air bronchograms Pneumonia of the LUL

When the entire lung is removed, there is volume loss on the pneumonectomized side The hemithorax eventually fibroses and becomes opaque Clues: There is frequently a resected fifth rib and/or surgical clips Lt. neumonectomy

The left hemithorax is opaque There is a shift of the heart and trachea toward that side indicating volume loss The left 5 th rib has been resected Pneumonectomy on the left

Which is this? Atelectasis Pneumonia Effusion
