- Causes of bilateral airspace opacities
Acute bilateral airspace opacification is a subset of the larger differential diagnosis for airspace opacification. An exhaustive list of all possible causes of acute bilateral airspace opacities is long, but a useful way to consider the huge list is via the material within the airways:
- infections, including aspiration
- fluid (primary differential if there is cardiomegaly)
- blood
- emboli
- alveolar sarcoidosis
- ARDS
