Upper lobe pulmonary fibrosis
Upper lobe predominant pulmonary fibrosis can be associated with a number of pathologies. These include
- cystic fibrosis: see pulmonary manifestations of cystic fibrosis
- pulmonary sarcoidosis
- Langerhans cell histiocytosis
- pulmonary tuberculosis
- pneumoconioses
- allergic bronchopulmonary aspergillosis
- chronic hypersensitivity pneumonitis
- histoplasmosis
- progressive massive fibrosis
- certain drug-induced lung disease
- carmustine (BCNU) chemotherapy
- ankylosing spondylitis
- pleuroparechymal fibroelastosis
Unilateral upper lobe fibrosis
The following disease processes can result in unilateral fibrosis, which may involve the upper lobe:
- radiation-induced pulmonary fibrosis: if the upper lobes have been irradiated
- as a complication following lung transplantation
