thickening of bronchovascular bundles

Thickening of bronchovascular bundles is a chest CT imaging feature that can be observed in a number of entities. It has some overlap with the terms peribronchovascular interstitial thickening and peribronchovascular thickening.

Pathology

Causes

Conditions that can result in bronchovascular bundle thickening include:

• sarcoidosis - see pulmonary manifestations of sarcoidosis 
  • classical condition to give this appearance
  • the incidence of thickening in sarcoidosis may be inhibited by smoking

• pulmonary interstitial edema
• certain types of pneumonias - pneumonitis
  • mycoplasma pneumonia
  • acute eosinophilic pneumonia
  • lymphoid interstitial pneumonia
• microscopic polyangiitis 
• lymphangitis carcinomatosis
