Question

Quizplus · Accepted Answer

The air bronchogram sign is a common radiographic finding on chest radiographs of patients with respiratory distress syndrome (RDS), which occurs when air-filled bronchi are surrounded by collapsed alveoli. The sign is particularly evident in patients with diffuse alveolar damage and consolidation, which are hallmarks of RDS. Enlargement of heart, fluid in apices, and elevated diaphragm are not typical radiographic signs of RDS.
