- What is the standard mnemonic approach for systematically reviewing a chest radiograph?
Show answer
ABCDE: Airway, Bones, Cardiac, Diaphragm, Everything else (lungs, pleura, tubes/lines)- What does a positive silhouette sign indicate on a chest x-ray?
Show answer
Two structures of similar density are in direct contact, so their normal interface disappears- Loss of the right heart border on CXR suggests pathology in which lobe?
Show answer
Right middle lobe- Loss of the left heart border on CXR suggests pathology in which lung segment?
Show answer
Lingula of the left upper lobe- Loss of the right hemidiaphragm outline on CXR suggests pathology in which lobe?
Show answer
Right lower lobe- Loss of the descending aorta outline on CXR suggests pathology in which lobe?
Show answer
Left lower lobe- What radiographic finding characterizes right upper lobe collapse?
Show answer
Elevation of the minor fissure and right hilum, with increased density near the apex- What radiographic finding characterizes right middle lobe collapse?
Show answer
A triangular opacity along the right heart border, best seen on the lateral view- What is a classic appearance of left upper lobe collapse?
Show answer
A hazy, veil-like opacity over the left upper lung with relatively preserved lung markings- What is the 'sail sign' on a chest radiograph?
Show answer
A triangular opacity behind the heart caused by left lower lobe collapse- What happens to the trachea and mediastinum with complete lung collapse?
Show answer
They shift toward the side of the collapse- What does the 'Golden S sign' indicate on a chest radiograph?
Show answer
Right upper lobe collapse around a central obstructing mass, forming an S-shaped fissure- What is the hallmark radiographic pattern of lobar pneumonia?
Show answer
Homogeneous airspace consolidation confined to a lobe, often with air bronchograms- Does uncomplicated pneumonia typically cause volume loss on CXR?
Show answer
No, unlike lobar collapse, pneumonia usually preserves lung volume- What pediatric pneumonia pattern can mimic a mass on CXR?
Show answer
Round pneumonia, a spherical focus of consolidation
