Bird fancier lung
Bird fancier lung refers to a type of hypersensitivity pneumonitis occurring as a response to avian antigens (usually inhaled proteins in the dust of bird feathers and droppings). It can have acute, subacute and chronic clinical presentations.
For a broad discussion on this entity, please refer to the main article on hypersensitivity pneumonitis.
HRCT chest features can differ depending on whether it is acute, subacute or chronic but in general can be similar to other forms hypersensitivity pneumonitis.
Described CT features include 6
- diffuse centrilobular nodules
- ground glass: diffuse or patchy predominant in upper lobes
- fibrosis with or without traction bronchiectasis
- mediastinal lymphadenopathy
Treatment and prognosis
Cessation of avian exposure forms a key part of management. Most cases have a good prognosis following cessation.
