Chronic bilateral airspace opacification is a subset of the differential diagnosis for airspace opacification. An exhaustive list of all possible causes of chronic bilateral airspace opacities is long, but a useful framework is as follows:

inflammatory
- sarcoidosis
- Wegener's granulomatosis
- eosinophilic pneumonia
- cryptogenic organizing pneumonia, formerly bronchiolitis obliterans organizing pneumonia (BOOP)
- polyarteritis nodosa (PAN)
- Churg-Strauss syndrome

infective
- tuberculosis
- fungal lung infection (especially in immunocompromised patients)
- incompletely treated infection

neoplastic / lymphoproliferative
- lymphoma
- lymphoid interstitial pneumonia (LIP)
- bronchoalveolar carcinoma (BAC)
