Bronchial diverticulum

A bronchial diverticulum refers to a blind-ended outpouching arising from the bronchial tree

They are relatively common on CT studies. They are more common and more widespread in smokers 2 but can also present in non-smokers. There may be a slightly increased male predilection but no significant age predilection 3.

They can be of variable shape and size although most tend to be around 1-2 mm in size 3.

Their exact aetiology is variable but chronic inflammatory tracheobronchial changes and increased endoluminal pressure may play a role in their development 4.
