Air bronchogram refers to the phenomenon of air-filled bronchi (~~~~dark~~~~(dark) being made visible by the opacification of surrounding alveoli (~~~~grey~~ - ~~white~~~~(grey/white). It is almost always caused by a pathologic airspace ~~(alveolar)~~/alveolar process, in which something other than air fills the alveoli. Air bronchograms will not be visible if the bronchi themselves are opacified (e.g. by fluid).

Air bronchograms can be seen with several processes~~, including the following~~ :

pulmonary consolidation
pulmonary oedema
non-obstructive atelectasis
severe interstitial lung disease
neoplasms - : bronchioloalveolar carcinoma; pulmonary lymphoma
pulmonary infarct
normal expiration

The air bronchogram indicates patent proximal airways.

Air ~~bronchogams~~bronchograms that persist for weeks despite appropriate antimicrobial therapy should raise the suspicion of a neoplastic process. CT ~~or guided biopsy~~ may be planned in such cases.
