Morphological description
Describe extent, central or peripheral distribution, symmetry and associated signs rather than simply naming the opacity.
Causes and diagnostic direction
Partial alveolar filling, interstitial thickening or reduced aeration can produce this finding.
Differential diagnoses
Oedema, infection, haemorrhage and inflammatory pneumonia are possible; ground-glass opacity does not necessarily mean active inflammation.
Pitfalls and limitations
Insufficient inspiration and dependent opacity may mimic disease; verify persistence with an appropriate acquisition.
Take-home message
Ground-glass opacity is a descriptor: distribution, accompanying signs and context narrow the differential.
