What is peribronchial thickening?

Peribronchial thickening refers to the increased thickness of the bronchial walls, often seen on imaging studies like CT scans. This condition can indicate inflammation, infection, or chronic lung diseases such as Asthma or bronchitis. It may also be associated with conditions like pulmonary edema or interstitial lung disease. The presence of peribronchial thickening can help clinicians assess the underlying cause of respiratory symptoms.
