Acute unilateral airspace opacification is a subset of the differential diagnosis for airspace opacification.
Differential diagnosis
The exhaustive list of all possible causes would be huge, but a useful framework includes:
-
pus (i.e. pulmonary infection)
-
fluid
-
blood
-
anticoagulation
bleeding diathesis
-
emboli
amniotic fluid embolism: usually bilateral
-
cells
