pneumonia • The hemithorax is opaque and there is no shift of the heart or trachea There may be an air bronchogram sign present
atelectasis • Atelectasis of an entire lung = loss of volume of the affected lung • Visceral and parietal pleura do NOT separate from each other • There is a shift of heart and hemidiaphragm toward side of opacification (toward side of volume loss)
Effusion • 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
Postpneumonectomy • 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
