[1] [4] studied the tumour-bronchus relationship and described five types: [1]
Usually, this condition resolves over 24–72 hours. Treatment is supportive and may include supplemental oxygen and antibiotics.

Air bronchograms is defined as a pattern of air-filled bronchi on a background of airless lung, and may be seen in both benign and malignant nodules, but certain patterns thereof may help in risk stratification.
The air bronchogram sign, where branching radiolucent columns of air corresponding to bronchi is seen, usually indicates air-space (alveolar) disease, as from blood, pus, mucus, cells, protein surrounding the air bronchograms. This is seen in Respiratory distress syndrome [9]
