air bronchogram
• 6 causes : lung consolidation, pulmonary edema, nonobstructive atelectasis,• severe interstitial disease, neoplasm, and normal expiration.
Pul. Edema :cardiogenic , noncardiogenic
• cephalization of pulmonary vessels, Kerley B lines or septal lines, peribronchial cuffing, "bat wing" pattern, patchy shadowing with air bronchograms,fluid in fissure , pleural effusion and increased cardiac size.
Posterior Mediastinal Mass
• ddx : neoplasm, lymphadenopathy,aneurysm, lung mass, neurenteric cyst,meningocele, and extramedullary hematopoiesis
